Features
CTS TENSION SYSTEM
The CTS is a combination of elastic tension rubber that controls the length of the shoe and soft high friction rubber that surrounds the forefoot. The soft M50 rubber evenly distributes power around the toe area and reduces pressure on the little toes. The harder tension rubber supports the big toe area and inside edging zone and is directly connected to the heel. The result is outstanding strength and precision on small footholds.
REINFORCED ELASTIC BAND (REB)
Reinforced Elastic Band is a technology used exclusively on the Instinct SR. Elasticated rubber is applied to the stretch gauntlet over the forefoot providing a snug performance fit while also preventing the upper from overstretching.
