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.
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.
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.
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.
