The term “UCBL” stands for University of California Biomechanics Laboratory.

A UCBL orthotic is a type of custom foot orthotic that is designed to provide support and control for the foot and ankle. It is often used to manage various foot and lower limb conditions, particularly those related to excessive pronation (rolling inward) of the foot.

This type of orthotic is commonly prescribed for conditions such as flat feet or flexible flatfoot deformities, as it helps to support the arch and improve the alignment of the foot.
