Learn To Run

The purpose of the Learn To Run Initiative is to teach runners a proven, effective, and safe way to run so they can avoid injury & run faster with less effort. Good technique, once mastered, allows you to run with increased efficiency, reduced fatigue, & less risk of injury.

You would get lessons for any other sport, right? Running, like any sport, can be done with both effective and ineffective methods. Altra aims to implement running technique classes all over the country to coincide with the launch of our shoes to help runners learn to run easier, faster, & more injury free. We are born to run, however, our bodies still need to be in proper form to be the most efficient.

Running Technique Basics

When running the body should be in an upright position, balanced in a forward lean from the ankles. The core should be locked with good posture & a straight back. The chest should push forward slightly as your arms pump backward while your hips and knees extend.

Hands should stay near the chest with a short, compact, arm swing. Pump the arms back and let them recover or relax forward. To help the legs drive straight and the foot to land aligned underneath a bent knee, the arms should go forward and back with as little side to side sway as possible and the elbows should not cross forward pass the torso unless running at very high speeds. The upper body should carry over the foot leaving your feet to lift off quickly and extend behind your center of gravity. The feet should strike the ground under a bent knee as the leg begins to swing back under the body. Although the foot will contact the ground slightly in front of the body, it will feel as though it is directly underneath. For most, the full foot should typically contact the ground at the same time (a midfoot strike). However, depending on genetics, the type of footwear being warn, and the running surface, the feet may contact with a slight forefoot landing or very slight heel landing.

Foot strike should be light and quick with around 180 steps per minute cadence. Running barefoot can greatly aid in helping you to understand & master proper running form.

Injury Prevention Tip:

Aim to run at least 1/3 of your mileage on natural or uneven surfaces such as grass, cobblestones, or dirt trails-this will balance your muscle structure & strengthen your stabilizing muscles.

Right now, many running stores teach running technique classes, ask your local store! If they don’t have a class, encourage them to start one. There are many good ways to learn proper technique, here are a few of our favorites:

Altra also encourages all runners to do at least some barefoot running. Running truly barefoot teaches proper technique, strengthens feet, and has a multitude of other benefits.

How To Transition



A lifetime of wearing shoes with elevated heels has neutralized your Achilles and lower calf muscles. They will need some time to redevelop! Depending on your foot and calf strength, many runners will experience some lower calf tightness for a few days to a few weeks when transitioning to a Zero Drop platform. This is caused by the lower leg loading farther and lower than it would in a shoe with an elevated heel.

This additional loading allows the leg to push off the ground more powerfully and activate different parts of the lower leg muscles. This can cause tightness, but it's a good thing! It's evidence of how much power traditional shoes were robbing from your stride. Once your muscles adjust, your lower legs will be stronger, more powerful, and more dynamic.


This transition guide is for moderately cushioned Zero Drop shoes such as The Instinct and Lone Peak. Higher cushioning models will require very little transition time. Light cushioning models provide greater strengthening of the legs and feet, but require a much longer transition time. While the average Altra customer transitions to one of our moderate cushion shoes in about three weeks, transition times will vary by age, tendon elasticity, and other factors.


Similar to any time you introduce a new shoe in to your routine, we recommend rotating your new Zero Drop footwear with your old shoes for the first few weeks. Start using them on short, easy workouts at first, and then work your way up to harder workouts. Try this schedule to allow your muscles and tendons the necessary time to adapt back to their natural state:

Transition Schedule


If you experience any discomfort or excessive soreness, reduce your mileage or intensity to allow your body the necessary time to adapt.

Working on your form will greatly help your transition. Take a running technique class, video yourself, watch world-class runners, or be actively engaged in fine-tuning your running technique. Check out for more information. We also recommend strengthening your feet. Exercises such as pulling a towel in with your toes, standing on one foot, and running barefoot will help give you strong, dynamic feet. Just make sure to ease in to it. After a successful transition, you are on your way to becoming a stronger, healthier and better runner!

FootShape™ toe box Transition

Wearing a shoe with a FootShape™ toe box is a whole new experience! It should not feel like a traditional shoe and will likely feel too loose in the forefoot at first. We recommend fitting your shoes with a thumbnail's width (about 2/3") between your longest toe and the end of the shoe. This may be more room than you are used to, but giving this room will allow your feet to be more relaxed and powerful. If the fit is correct, the shoes will likely feel "too big" around your toes, while being secure from the ball of your foot back through the heel. Most people get used to this feeling in a few hours to a few days. Proper toe box fitting can help eliminate black toenails, blisters, and foot fatigue.

FootShape™ toe box Challenge

Once you've completely and safely transitioned to the Zero Drop™ platform, you're ready for the FootShape™ toe box challenge. For 30 days, wear only your Altra's and lifestyle shoes with a FootShape™ toe box. This will allow your toes to relax, spread out and become stronger in a natural position.

The FootShape™ toe box challenge allows the feet to regain their natural shape and function. Most people's feet unfortunately start to look like the shoes they wear, tapering at the toes rather than continuing to splay. This change in foot shape is similar to Chinese foot binding and robs the feet of their natural ability to stabilize and push off the ground powerfully. Additionally, feet shaped from tapered shoes are more prone to foot problems such as plantar fasciosis, bunions, neuromas, and nerve pain.

After taking the challenge, you will feel just how much tapered toe boxes have restricted your movement, bound your feet, and robbed them of comfort, power, and stability.

To enhance the experience, Correct Toes can be worn inside your Altra shoes and can help your feet regain their natural shape. They are also helpful in reversing the effects of bunions, plantar fasciosis, and other foot and leg problems. For optimum foot health, Altra recommends wearing only shoes with a FootShape™ toe box at all times possible.

FootShape™ toe box

FootShaped™ Design


Traditional running shoes feature pointy toe boxes that squeeze the toes out of their natural position–increasing risk of bunions, hammertoes and plantar fasciitis. Altra's FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position. This enhances stability and creates a powerful toe-off to maximize running performance. We wish we could call it some scientific breakthrough, but we're simply giving your foot the working space it needs.

  • Keeps big toe straight for greater stability and a more powerful toe-off
  • Allows toes to relax and spread out naturally
  • Allows foot to naturally stabilize excess pronation


The human foot is an anatomical masterpiece. It's designed for stability, speed, and to get you from point A to point B. At Altra, we choose not to mess with perfection and simply let your foot do its thing. Every Altra shoe features a last that has been molded around the healthy position of a human foot. A shoe last is a 360-degree model of a foot used to create the shoe's heel, instep and toe box dimensions. Unlike other shoe companies that alter the last to make the shoe look more sleek and fast, we've chosen to let your foot decide the shape of the shoe.

Zero Drop


Every Altra running shoe features a fully cushioned Zero Drop™ platform that places the heel and forefoot the same distance from the ground. This natural balance aligns the feet, back and body posture for less impact. It also strengthens the Achilles and lower calf muscles that have been weakened over a lifetime of running on elevated heels.


  • Heel and forefoot are the same distance from the ground
  • Promotes proper form to reduce initial impact by 3–5 times.
  • Natural Achilles loading for better propulsion
  • 1-to-1 ratio naturally aligns feet, back and body posture
  • Encourages better running technique
  • Weight-balanced from front to back
Average feet transition


Altra's complete line of Zero Drop footwear separates us from most running shoe companies that feature shoes with elevated heels. Running in elevated heels removes the foot from its natural position and encourages high-impact overstriding.


After countless customers entered his family running store complaining of pain and injury, Altra founder Golden Harper felt compelled to develop a solution. His college research on running injuries, combined with video analysis of running technique, made it easy to see the design of traditional running shoes promoted poor form and excessive impact.

Using a toaster oven, he began to melt the outsoles of customers' shoes and carve out unnecessary heel cushioning. It was ugly, but it worked! Harper coined the term "Zero Drop" to describe the level cushioning and perfect weight balance from heel to forefoot.

Runners immediately felt the difference. It was their results and running success that fueled the creation of Altra Running.


Altra Running is the only running shoe company to provide a complete line of fully cushioned Zero Drop running shoes. Our lightweight blend of EVA and A-Bound™ cushioning runs evenly from heel to toe and is weight balanced from front to back to encourage proper low-impact running technique.

Gender Specific

Gender Specific Footwear by Altra

Women's feet are anatomically different than men's feet. Women have a narrower heel and midfoot, higher instep, longer arch and unique metatarsal spacing. While this has always been a fact of life, traditional running shoe companies have opted to make male and female shoe models virtually identical for years.

Altra is the first shoe company to introduce an entire line of truly female specific shoes. Every last of Altra women's running shoes have been molded around the unique shape of the female foot. A shoe last is a 360-degree model of a foot used to create the shoe's heel, instep, arch and toe box dimensions.

Female specific design combined with a cushioned Zero Drop platform and FootShape™ toe box allows a woman's foot to remain in a natural, relaxed position throughout her run.

Fit & Feel

The Fit

Having a proper fitting running shoe goes a long way when you are running long distances. This key reason is why we engineered our footwear the way that we did. It is imperative to have a proper fit for your feet to run as natural as they are able. When going around barefoot there is no constraint on the foot. The toes splay, the foot relaxes and more power is put into the muscles.

To maximize the benefits of Altra Footwear, we encourage you to follow these fitting suggestions:

  1. Please allow at least ½ inch between your longest toe and the end of the shoe.
  2. Your Zero Drop Footwear should feel as relaxed and natural as possible.
  3. If fit is correct, it may feel "too loose" around your toes and may take a day or two for your feet to get used to spreading out.
  4. Fitting this way will allow your feet to become more STABLE, more COMFORTABLE, and more POWERFUL.

By following proper fit and footwear you then let your body do what it is naturally inclined to do. There is no need for additional stability, supports, airs, gels, shocks, or the other. You then have a running experience that will reduce injury while running longer and further.


Altra BareSole™

Build stronger feet and legs by wearing shoes without an insole. Designed to be worn without a footbed, these shoes allow for more room and offer less cushioning so you utilize more muscles.

Strengthen Footbed

Allow your feet to build strength and support with 3 mm of flat insole. For those new to Zero Drop™ technology, this footbed should be broken into slowly. Transition to the strengthen footbed by first wearing it on shorter runs and gradually working up to your regular mileage. For those with stronger feet, transitioning to the strengthen footbed should be easier.

Support Footbed

Providing some arch support, this 5 mm support footbed gives you the feeling of a more traditional insole. For those new to Zero Drop™ technology, this insole is a good place to start.

Stability Wedge

The Altra stability wedge allows for maximum stability without pressing into the arch and weakening the foot. Unlike traditional stability systems that only provide stability underneath the arch, the full-length 4 mm varus, angled from the outside to the inside of the shoe, runs evenly from heel to toe and accounts for both early and late stage foot collapse. The stability wedge sits underneath the insole of the shoe and can be used in both shoes or a single shoe for those who have collapse on just one foot.



Maximize proprioception with this minimalist sole. Crafted from siped performance rubber, this thin sole layer measures 3.4 mm.

TrailClaw™ Outsole

This outsole positions the strongest canted lug traction directly beneath the met heads with follow up 'claws' positioned near the front of the shoe. The combination of the unique uphill and downhill traction in combination with sticky rubber makes the TrailClaw™ Outsole a beast in any trail condition.

FootPod™ Outsole

For maximum flex and responsiveness, this outsole maps the bones and tendons of the human foot. With canted lugs mapping your foot, this unique outsole provides a natural, all-purpose traction system for a variety of surfaces from road to treadmill to dirt paths.


Alternate Lacing

For runners with a wider forefoot, or those just looking for more space for their feet to relax, we’re sharing our customer preferred and personal favorite lacing system. This unique system allows the forefoot to expand and breathe while securing the heel and preventing “lace creep.”

  1. Start by running the lace straight across the bottom, over the tongue and downward into the shoe. Make sure both sides of the remaining lace are equal.
  2. Without crossing, skip under to the second set of holes, then over to the third set of holes.
  3. From the third holes to the fourth holes, cross the laces over the top of each other and insert downward into the holes on the opposite side. Continue this crossing technique until you reach the second-to-last set of holes.
  4. String the lace into the last holes upward from underneath. Create a small loop with each end by threading the lace back into the same hole.
  5. Slide the remaining lace from the opposite side into the hole.
Alternate Lacing
    Other Recommendations:
  • We recommend that the laces over the top of the arch/instep are loose enough to comfortably fit your finger after the shoe is tied.
  • The lacing should fit snuggly at the heel, relaxed over the arch and roomy at the forefoot.
  • It may feel "too loose" at first. That’s good! Your foot will learn to spread out and relax.
  • At first, try lacing only one shoe and going for a run. After a few miles, you may notice that the newly laced shoe keeps your leg more relaxed than the other leg sporting the traditional lacing. If the foot muscles can relax, there is a chain reaction that affects the entire the leg.
