The original production orientation of dunk sb series is low-end skateboarding and high-end leisure, so it requires good fit and fixity. The lining is thicker than ordinary shoes, so it is sometimes recommended to squeeze your feet. In fact, the inner length is standard, and it is ok to buy a normal size if the feet are not too wide. It will be very comfortable after the running-in period. However, because the lining is thicker, it will be a little hot in summer, but the low pole is much better. This year, Nike launched DUNK SB ishod wair signature shoes with thin tongue lining, which are suitable for summer wear.
