Any suggestions for good non-leather/suede hiking shoes?
First things first. Find a manufacturer who has a last that is designed for you type of foot. It might take several trips to a number of places but this is crucial. Have someone measure your feet. One is typically longer than the other and a little larger volume wise.
Depending on your location, if you can find a quality boot fitter there are no limits. They can stretch or punch certain areas to customize the fit.
Once you find a "Brand" then pick your materials. If in a dry place you can probably avoid GOR-TEX. It is great but it doesn't breath as good as they say. Also highly recommend Smart Wool socks. They come in various types for all kind of hiking.
A good idea if your close to one is look up Surefoot. They can make your feet feel like nothing else.
