I have the rider 20 GTX shoes and I really like them for running in the winter. Keeps my feet warm and dry in the snow. They don’t work great if it’s pouring rain so either don’t run or just wear normal running shoes if it’s really wet out. At least they made the rider 21 GTX shoes a normal color - the rider 20’s came in lime green (men’s) and bright coral (women’s). I’m still deciding if I’m going to buy these since my Rider 20 GTX shoes still have plenty of miles left on them.
