The curry ten is phenomenal. It has amazing traction, so much that it hurts me indoors. Outdoors it was fine, it held up ok, but just use it once in a while, or else the foam is going to get destroyed. It has a nice fit, and you don’t need to break it in but your feet might hurt a slight bit during your first session in these. I recommend these for people who want to be speedy, because they are extremely light and are shifty.
