Soft Touch Progressive Release bases are molded from durable cut resistant polyurethane. Made in the USA, all of our bases are designed to flex and absorb energy as a player slides into the base. In case of uncontrolled slides, the patented Progressive Release action allows the base to flex until enough force is applied to pop the base free from the mount unlike a stationary base. Proven in 20 years of play, Soft Touch bases outperform standard bases. Soft Touch bases are fully warranted against failure in craftsmanship and material for a full year.
