I've worn these a few times around the neighborhood, but they no longer fit, so I bought a new pair. I haven't used them in rivers or anything like that (*^^*) I think there's almost no deterioration of the Velcro or rubber parts. Please check the photos. The rubber parts look like they're reflecting light in the photos, but I think they're almost in new condition. If you have any questions, feel free to ask in the comments section!
