The APL TechLoom Chelsea brings your workout to new heights. Constructed using a newly developed 3D stretch rebound TechLoom upper, the slip-on design features a dynamic weave pattern that adjusts to the shape of your foot. The herringbone knit upper expands where you need extra range of motion while still holding snug in key areas of support. Internal reinforcements around the lateral and medial keep your foot centered on the footbed. The elastic stretch collar makes entry quick and easy, while the suede heel counter and pull-tab adds support.
