Soft Touch® “Progressive Release” bases are molded from durable cut-resistant polyurethane. Made in the U.S.A., all these bases are designed to flex and absorb energy as a player slides into the base. In the case of uncontrolled slides, the “Progressive Release” action allows the base to flex until enough force is applied to “pop” the base free from the mount, unlike any stationary base. Proven over 15 years of play, “Progressive Release” bases out-perform standard bases. Soft Touch® bases are fully warranted against failure due to defective materials for one full year.
