I fish felt soled boots with studs. There are several benefits of wearing these type of boots. The most obvious is traction on slippery riverbeds as well as muddy walks along the bank. Another great benefit of a felt soled boot is how much foot abuse they absorb. After fishing a day wearing my rubber lug soled hipboots my feet are beat, from contorting around riverrocks. After a day in felt soled wading boots, that are stiff and have that layer of felt between your feet and the rocks, my feet are in way better shape. I havn't had any problems with traction in slippery conditions wearing these boots, as long as you keep traction in mind. I will most definatly stay with felt/studded bottoms as long as I continue to fish.
