I just started using these boots, so this is my preliminary observation.
They run slightly large, but for me it's just enough to be able to use my plantar fascitis inserts, and also heavy socks, so that's good.
They are pretty sturdy, and don't hit me anywhere on the legs or anything; the fit around the legs is loose.
But I am worried that they won't be leakproof for very long; I am not sure they'll last very long; however, if they do, they will turn out to be a great value for the price!
