I purchased these as indoor shoes for the gym. The store staff recommended them as a product with excellent shock absorption for the knees and stability upon landing. They fit very well when I tried them on. However, because they are a wide 3E type, and I usually choose a size smaller, after wearing them about three times in the gym's indoor studio, the toes started to feel tight, so I stopped using them and am now selling them. Please check the size on the label in the photos. Color: Black系 (Black-based) Condition: No stains, tears, or odors.
