NIKE Running Shoes 26cm These shoes are made of mesh material, offering good breathability, a comfortable fit, and a lightweight design. The soft material makes it less likely for your toes to hurt. The design for lacing the shoes is also well-considered, allowing you to adjust the fit to your liking. I used these at the training gym. However, I've been busy with work and haven't been able to go to the gym consistently, so I haven't used them extensively. There is almost no wear on the soles. Since they were used indoors, there are no major noticeable stains, but there is some dirt on the insoles. I recommend washing them or replacing the cushions. These are stored items, but they are used. I have included as many photos as possible, but please refrain from purchasing if you have any concerns.
