The Science Behind Heel Pad XC: How Sorbothane® Absorbs Heel Impact

In tennis, every movement puts load on your body — and much of it lands on your heels. Heel Pad XC, developed by Road To Pro, was built to absorb that impact before it reaches your joints, without changing how your shoe feels.

A closer look at Heel Pad XC

Heel Pad XC is made from Sorbothane®, a viscoelastic polymer that absorbs up to 94.7% of impact shock (per Sorbothane® material spec). Originally developed for demanding engineering uses, it is now used to help protect the joints of players from the repeated shock of hard courts.

Heel Pad XC also targets a common but often overlooked problem in tennis and pickleball: heel sting. That sharp sensation comes when you defend or stretch for a wide ball and your heel pounds into a hard court. By placing Sorbothane® under the heel, Heel Pad XC absorbs that shock so you can move aggressively with less heel impact afterwards.

Beyond the court

Heel Pad XC was developed for tennis, but it works in any athletic shoe with a removable insole — for basketball, running on pavement, and other high-impact training on hard surfaces.

Built to last

Heel Pad XC has been tested over 1,000,000 steps with no compression set, so the cushioning you feel on day one is the cushioning you get months later. It comes with a no-questions-asked full refund within 30 days.
