The Spin II incorporates stretch canvas, soft wide elastic binding, and inner silicon to ensure a seamless fit. Half soles also feature wide elasticized binding along the top line and inner lined silicone to ensure a tight, non-slip fit. Outsole with ballet flat pleating allows toes to spread naturally and suede outsole allows for multiple turns with ease. The innovative fibers within the stretch canvas fabric will always recover to their natural shape.
My daughter dances competitively and she wears these half soles for contemporary classes and performances as well as the occasional informal ballet class. They are MUCH more comfortable than the similar shoes by another brand which have a narrower outside seam on the top of the foot. They are great for turns and my only complaint is that they do wear out quickly- toes poke out after a while. She's on her third set since in the last six months. We have been advised to avoid the leather half soles as they stretch out too easily.
I tried these split soles for the first time last night while teaching, and they were wonderful! The fit was great and the turning was even better. They looked beautiful on my feet, and didn't slip once! I highly recommend these to anyone and everyone.
