The Experience Form features:

The Experience Form is all about effortless and supportive miles, with a lightweight midsole, guidance technology, and a 4mm drop. Sail through daily workouts, crush long training runs, and smile through miles with the run club crew in a support shoe that’s ready to move. Lightweight and responsive compression-molded midsole foam encourages efficiency. It’s got GuideRail™ technology, which encourages natural foot placement with gentle guidance for an inherently stable ride. A low 4mm drop complements the shoe’s rocker shape geometry for an efficient toe-off and a smooth, quick roll through your stride. With Altra’s signature FootShape fit, you get a roomy toe box and a secure midfoot, so you can move the way you were designed to. Feel the glide in your stride with the guidance and performance you need.
