The Rock Stop® is a layer of dense material that’s placed in the forefoot section. Its purpose is to protect the underfoot from rough surfaces and trail debris. It also attenuates impact shock and diffuses the energy generated by such a force. A foam insole is placed above the primary midsole unit. It can be replaced or removed entirely.

The tongue and collar are padded. These two sections hold the foot in place and prevent it from wobbling inside the foot-chamber. Soft fabric lines the interior of this shoe. It’s crafted to stave off hot spots and skin irritation. A pull tab is placed on the back portion of the collar. This loop makes it easy to wear and remove the Summit Unknown.
