My go to shoe

Comments: Slipped on the 3-Sum straight from the box. Started running down the gravel road I live on. A warm breeze washed across my face. In an instant my mind flashed to my childhood. I was a kid again running barefoot in the long cool grass. That is how comfortable these shoes are. The color is pretty solid also.
The 3-Sum™ is the sum of the three event triathlon experience. Lightweight, fast, and lightly cushioned, the 3-Sum™ is built for triathletes who demand the ultimate in performance. With a seamless upper, easy-on transition pull-tabs, quick-draw lacing system and heel/forefoot drain holes, the 3-Sum™ minimizes transition time and maximizes performance. The Zero Drop™ design allows for natural loading of the calf and Achilles, while optimizing the landing angle to ensure powerful speed with minimal impact. The Altra 3-Sum™ – get off the bike and run like there is no tomorrow!
