I purchased these shoes to replace my Bloch boost sneakers. I am familiar with Bloch dance shoes so I ordered 1.5 sizes up from street shoes.  I should have gone up a full 2 sizes.  I think that this dance sneaker fits smaller than the boost.  The pivot point on the sole of the shoe is more plastic like and therefore more slippery.  I am wearing these sneakers to teach Zumba so I love the sliver color and look of the shoes. If you are looking for a sneaker for Zumba I would recommend the "Bloch Boost dance sneakers".  It has more cushion under the heel and just the right amount of pivot under the foot for a wood floor.  The twist is a good dance shoe if you dance on a marley dance floor.
