I bought these mainly for every day use walking the dog in snowy conditions. I live in the Yukon where this would be normal.But this winter all our snow has turned to ice so to be honest I haven't needed them yet. I tried them on over my light hikers and I could barely get the Velcro done up! I take size 9 women's so would not call myself a medium/large in a unisex product. However, I like that I don't have to put the gaiters on before I put my shoes on, which is the case with my running gaiters. And they appear well-made, if tight!
