The Fight Pro is everything that you could possibly hope for in sparring equipment. Ringstar"s patented R3 Technology absorbs impact incredibly well. The Ankle Advantage System in the Fight Pro provides additional ankle support. These are said to be the most high-performing sparring shoes ever. Joe declined to comment on the matter but smiled. These shoes are approved for competition by the NASKA, IKF, ISKA and 60 other sanctioning bodies.
