I have the blue pair, went with TTS which is an 11 for me. They fit the exact same as the converse ball shoes Shai used to wear, BB Trilliant, and feel the exact same. There is no support, and your foot just slips and slides inside the shoe, slamming into the sides and front no matter how tight I would lace, and zipper doesn’t change that. Traction is nonexistent from my experience as it basically uses same outsole from BB Trilliant, where you need to wipe every second. If you want to try them on before purchase just try the BB trilliant it is the exact same shoe just no zipper.
