I buy a pair for a Kauai and Maui trip last March . I end up wear they everywhere for everything . I try they on in a shoe store so I get a perfect fit , which I highly recommend . I wear a size 10 normally and I have wide foot . these be 9 1\/2 and fit I perfectly . it be a little bit of effort to put they on and I normally do not cinch they down . if I be hike or need they totally solid for hike and the like , then I tighten they down . they be very comfortable either way . I stop notice they at all after a day or two . obviously they will not give ankle support , but for day hike with a day pack they be perfect . they be just right for Hawaii , which be so humid and muddy . I be constantly hose off my shoe . throw they in the wash machine and they look new again . they like any kind of fresh or salt water activity and they be very durable and of course very protective of you toe . I think they look very good , too . I put they on over thin nylon sock and then directly into my fin for snorkeling , since my fin have a large foot bed . just put on you fin and take off you fin . it be so convenient . the only complaint I have be that I do notice some foot odor , even though they be synthetic , after two week of daily use . I think my foot be probably less stinky than most people , but give the constant humidity and wet environment in a closed toe shoe , I do not blame the shoe and it be not that bad of a problem . you can just throw they in the wash machine when they start to smell , too . I still wear my old super durable and comfortable Teva 's for everyday stuff , but for anything else , short of backpacking , I put on my keen h2 's and forget about my foot .
