I've also got the Puma/Sparco Speed cats, and they are one of the most comfortable shoes Ive ever worn, and probably the funkiest, but I find theyre not suitable for dancing, I find that after a few hours of dancing my feet get a bit sore, since they dont have any cushioning, its pretty much thin rubber, then your foot.
Could just be the way I dance though...
Currently still using my old Vans, but theyre getting holes in them, so Im also in the market for new shoes.
