Carbon fibre UCBLs for Hypermobile Flat Feet
Swipe to see the difference.
Before Fitting: both heels rolling inwards, arches collapsed, and the classic “too many toes” sign from behind. This is pes planovalgus in an adult with joint hypermobility, where the ligaments simply don’t hold the foot’s alignment under load.
After Fitting: the same patient standing in his new orthotics. Heels vertical, arches supported, ankles stacked over the feet.
The devices are custom UCBLs (University of California Biomechanics Lab orthoses) laminated in carbon fibre. The deep heel cup and high medial and lateral walls grip the hindfoot and midfoot and hold them in a corrected position, rather than just propping up the arch the way a standard insole does.
Carbon fibre keeps the orthotics thin and rigid enough to control a hypermobile foot without taking up the whole shoe. Finished with a cushioned top cover for comfort.
For hypermobile patients, the goal is control: less strain on overworked tendons and ligaments, less fatigue, and a foot that doesn’t collapse a little more with every step.
Custom made in our Claremont lab, from cast to fitting.
