Most recommended style by coaches and trainers: there is a 3/4" platform... and this style has the second/top strap around the front to hold your foot against the shoe. This offers the support of the ankle strap, without the hassle of the buckle.
5" clear heel.
This style has a rubber sole for grip and you can add on the removeable ankle straps to have in your bag in case they are needed.
*Not Approved for shows that require no platform*
After your show... use a Mr.Clean Magic Eraser to clean of surface tan from the sole and plastic
