Lug sole
Also called rubber sole, Vibram sole
A molded rubber outsole with deep tread blocks, like a hiking boot. Legal everywhere and better on banks and trails.
Rubber lug soles are the default on modern wading boots, partly because of felt bans and partly because most anglers walk a long way before they wade. On dry bank, mud and trails a lug sole is much better than felt.
On wet algae-covered rock it is worse, and there is no honest way around that. Sticky rubber compounds have narrowed the gap and not closed it.
The standard fix is to add studs, which turns a rubber sole into something that competes with felt on the worst footing while staying legal and drying overnight.
Not all rubber is the same. Sticky compounds developed for climbing shoes, and Vibram's fishing-specific soles, grip meaningfully better on wet stone than a hard hiking compound, and they wear faster in exchange.
Check the sole has stud ports before you buy. Retrofitting studs into a sole that was not drilled for them is possible and much less reliable.
Buy rubber, then add studs if you fish slick rock. That combination is legal everywhere and covers nearly all conditions.
