Because they are fake shoes, they are cheap. Generally speaking, it's not bad. It is the aj series sneakers with the best foot feeling that I have worn so far. All-bottom zoom air cushion and midsole carbon board, plus the uppers are woven fabrics, the comfort is absolutely ok. However, this pair of shoes also failed here. Woven fabric is too soft, lacking basketball shoes and necessary support. Therefore, this model is also positioned as an off-court shoe for my personal fitness.
