These are good for biking or walking, but the velcro straps make anything more vigorous ill advised. I don't do much more than bike or walk so they work for me. They are appealing for several reasons: they looks goodm they are comfortble with or without socks and they provide a nice amount of support. They seem to run a little large and I am sure these straps will wear out soon. If i get them again, I will go a half size smaller so I can cut the straps off and continue to wear them. For the price, you can't go wrong.
