Formally known as the AltraFWD Experience, the Experience Flow Running Shoe brings us effortlessly smooth miles on road. The rockered midsole works with the 4mm heel-toe drop to roll our strikes into springy toe offs, while the light, streamlined upper gives our midfoot a snug hug, and Altra's Standard FootShape Fit gives our toes plenty of room to splay naturally throughout our transitions. As the miles tick by, the compression-molded midsole foam keeps us floating.
