The Crazy Big Bloc Pro is a dual-density toe stop with a large footprint and tons of stopping power. Elevating the performance and durability of the popular Big Bloc Toe Stop, Crazy layered a red, softer compound underneath their traditional rubber compound. This allows the toe stop to maintain the same great response and feel Big Blocs have always offered but now with a better grip on slippery surfaces and more stopping force as soon as it touches down!
