An insertable midsole orthotic (145) removably inserted within a shoe upper (21) and sole (28), having sides (185) which hold it in position. The sole (28) having concavely rounded sides (28a) which may be formed in part by the insertable midsole orthotic (145). The insertable midsole orthotic (145) may extend the length or form only part of the sole (28) and can incorporate cushioning or structural components (188). The insertable midsole orthotic (145) provides the capability to permit the replacement of the midsole material, when degraded or worn, to maintain optimal characteristics of the sole (28) or to allow for customization of the sole for individual wearers. The sole can also include at least one compartment (192) containing fluid, a flow regulator (210), a pressure sensor to monitor the pressure in the compartment, and a control system (300), such as a computer processor, capable of automatically adjusting the pressure in the compartment in response to the impact of the shoe sole (28) with the ground surface. |
