I bought these last summer and wore them alternately with other sneakers. My child seems to want shoes that can make them run fast, so I bought these. They are light and easy to put on and take off. I wash the sneakers on weekends, so there isn't much noticeable dirt, and I think they can still be worn, but please understand that these are USED. The following is quoted from the HP: These shoes are designed to handle any run or jump with exceptional soft foam and flexibility, so you can play anytime. These sustainable shoes are made with over 20% recycled materials, considering the environment. With straps and elastic laces, it's easy for children to take them on and off ◎ [Specs] Breathable recycled mesh and a seamless upper with reduced seams enhance the fit and lightness. The foam on the opening and tongue provides a comfortable fit. Soft midsole foam enhances cushioning and underfoot support, reducing the impact of each step. Overlays are added to the toes for stability and durability. Color: Black系 (Black-based)
