Summary

This trial tests the Nike Sport Sole, an accessory that attaches to the Cheetah Xceed running prosthetic foot. The sole comes in two versions: a traction sole for general running and a spike pad for track use. Researchers will have three people with below-knee amputations use the sole for 6 to 8 weeks, then inspect it for wear and tear. The goal is to see if the sole holds up well and is easy to use during running.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Nike Sport Sole, an attachable and detachable accessory for the Cheetah Xceed running prosthetic foot, available in traction sole and spike pad versions
What this could lead to
If the sole holds up well, it could offer runners with below-knee amputations a more durable and comfortable option for training and competition.
What could go wrong
This is a small, early-stage study with only three participants, so results may not apply to all users. The sole might show more wear than expected or not fit every prosthetic setup.
