Wore them first timekayaking in Lake Osborne, Lake Worth Fl. They are very lightweight & easy to put on & off. I like the easy adjust elastic laces. The insole does not remove as in my previous 6 yr old North Face. I did not wear my socks this time & found that sand & small stones started irritating my heels right away. With my old ones my foot was always elevated & small debris lodged under or at the sides of the insoles. These new ones apparently are anti-microbial so the next time I'm in salt water/or guck I'll update my review. My old ones always smelled. They seem to dry faster also. Size wise I took a full size smaller but width, medium was just fine. If I can get another 6 years from these I will be more than pleased as the price $60, Free shipping & Returns was $40 less than my first ones. Liked the fact that I could order 2 different sizes, try them on & then send back 2nd pr. In my case I returned them on a Monday & they received them same day through UPS & my credit was less than a week! Can't beat that customer service.
