text: I just wore a pair of these to Zumba and I'm disappointed.  There is no support and not enough cushion so my knees and  back hurt.  The toe box is too wide for my foot so my toes hurt as well. Also, the pivot point is not slippery, it is the same material as the rest of the sole so it kind of sticks a bit.  They are stylish and beautiful shoes and comfortable to wear around to the grocery store and light exercise things, but in my opinion, not suitable for serious workouts.  The search for the perfect Zumba shoe continues.  My last pair were Nike and they were a little snug but had excellent support and the pivot point was made of rubber so dense it felt like plastic so spinning was a breeze, but I don't seem to be able to find them again; perhaps they aren't being made anymore.
