An outsole has a roll-up portion protruding upward from a peripheral edge portion of an upper surface of the outsole. The roll-up portion is located at a portion corresponding to the expansion portion of the midsole and covers a peripheral edge portion of the expansion portion from the outside.

A rearfoot support device is provided that extends upwards on both medial and lateral sides of the heel in order to stabilize the subtalar joint in a neutral position and reduce medial longitudinal arch collapse. The device supports the subtalar joint by cradling the heel on the medial and lateral sides to prevent the subtalar joint from deviating excessively from the neutral position. Unlike conventional orthotic support devices, the rearfoot support device includes a clamp closure system to accommodate different foot widths, which securely clamp the device to the rearfoot of a user and support the subtalar joint without the need for fasteners or wrapping around the midfoot or dorsum of the foot. The device fits securely to the heel and rearfoot, and can be worn barefoot, with backless footwear or with enclosed footwear to provide improved subtalar joint motion control.
