Vivos are awesome! They last and they have a very puncture resistant sole. great for when you want a shoe that doesnt make you look like a tree frog. MBT are total crap, worst idea ever. Like training in orthopedic moonboots. Five fingers, gymnastic shoes, etc soft soles without ht are what count. If you want cheap go Asics Matflex w the gum sole. $30-$40 new and they are awesome. If you want minimalist the other main shoe i wear is the Feelmax Panka in black of course. zzzzzzzzzzzzzzz
