Run more naturally.

Crush the running segment of your next triathlon in the fast, feathery, and lightly cushioned Altra Men's 3-Sum 1.5 Running Shoes. A seamless upper, easy-on and off pull-tabs, quick-draw lacing system, and heel and forefoot draining holes, you'll be bombing down the road while other racers are struggling to tie up their bulky traditional running shoes. The 3-Sum features Altra's unique foot-shaped design so your toes can relax and spread out, a zero-drop platform to put your foot in the most natural position possible, and an outsole that matches the natural flex of the joints in your foot. 


Altra's Zero Drop design allows for a more natural foot landing angle for maximized power with minimized impact. With tons of triathlon experience, Altra's designers engineered the 3-Sum to reduce transition times while also reducing shin splints, knee pain, forefoot pain, and weak feet. Cushioned for hard running, shaped for comfort, and created for racing, this shoe helps to turn all-out efforts into podium finishes.
