I listened to the reviews and ordered a size up and am glad I did! Theres a little room in the toes with thin socks, but the width fits perfectly. With thick socks, they will be perfect as well! I am 59 and shoe size is usually a 9. I ordered a 10 (which I never have done) and they fit perfectly! Plus I feel like a snow bunny! These are the white nylon option- highly recommend!
