There are some signs of use, but the soles are not worn down and they can still be worn. These are high-performance sandals with a minimalist (streamlined structure) and motion (operation) concept, featuring a strap structure that achieves a high fit with the foot during walking and running. The webbing tape is made from 100% recycled material. The fit can be adjusted with two straps, making them easy to put on and take off. The bottom unit features a FASTFOAM™ technology footbed with excellent resilience and stability, and a cradle technology built into the midsole to suppress heel sway upon landing. The outsole is equipped with Vibram® Megagrip, which provides grip in muddy conditions. This is a unisex model. The North Face
