The Chaya Controller long stem toe stop is made of a mix of grippy natural rubber paired with long-lasting and durable synthetic rubber components. This toe stop is slightly harder than the Chaya Cherry Bomb stopper. This flat head stopper with its wide surface area of 48mm in diameter provides stability and predictable bite needed for acceleration and fast stops. To help reduce weight the Controller stopper comes with a long aluminum cast hollow stem. This toe stop won't leave marks on the floor and works great on all kinds of surfaces including wood. sport court. concrete. or asphalt.
