Given that most TM belts have a polyurethane top-layer, what make/model of shoe would be the best fit in terms of longevity and grab (no slipping on the belt!). I would imagine that a shoe with a rubber outer sole would be the best?
I realize that (myself included) whatever we run with out-of-doors is often what we run with inside on a TM, but is this the really best way to go? I've run on a TM with my Mizuno Wave Ronins wich have a weird plastic-like out sole, and I tend to slip and slide all over the place. Actually strained a calf on a TM with the Ronin's. Bottom line: What's the best shoe (if any) for TM running?
