The Adams O model is a boot created for the big stage. This boot is specifically designed to give you the edge on fight night. It is weightless and flawless when it comes to giving you natural movements in the ring. It has a thin rubber sole that will bend and adjust to your quickest movements, as well as a strong rubber surface to help you with traction and grip. The O model is our performance boot but we do not recommend it for running nor hard surfaces. It is strictly designed for ring use and to be trusted on the big fight night stage.
