I wear an 8 but ordered a 8.5 for the extra toe room needed for active pickleball. Should have kept it at 8 but the shoe was strong with excellent support for no rolling and ankle support. Gave the 8.5 to my daughter and ordered an 8 for me. Its just a hair longer than most asic 8s which is great to keep from jamming your toes. Came before the expected date
