The problem we engineered against

Every Hit Is a Vibration Your Tendons Have to Survive

1 in 3 recreational players develop tennis elbow. Standard dampeners reduce string sound, not the structural vibration travelling into the wrist and forearm. Hundreds of impacts per match. Cumulative tendon breakdown. The problem every other dampener ignores.

Our solution

Frequency-Specific Engineering. Not Noise Reduction.

We didn't set out to eliminate vibration — a numb racquet is unacceptable at any level of competitive play. Our goal with ShockSorb was more precise: preserve the vibrations that give you feel and control, and filter out the frequencies linked to joint discomfort and muscle fatigue.

ShockSorb® uses Sorbothane®, a visco-elastic polymer that behaves like both a liquid and a solid under stress. When vibration hits it, it deforms to absorb and distribute energy in all directions rather than reflecting it back into your hand.
Two years of R&D and over 200 material iterations identified the middle frequency zone that is mechanically clean for human biology, preserving racquet feel while filtering the frequencies linked to arm injury.

The Injury

Tennis Elbow

Every ball impact transfers 500–1,000g of vibration force up the racket handle. Without adequate dampening, this energy loads the lateral epicondyle tendon repeatedly, causing micro-tears and chronic inflammation.

The Technology

Sorbothane®

Most cushioning materials only change how an impact feels, not how much of it actually reaches your body. Sorbothane works differently: its visco-elastic structure absorbs the impact energy itself — whether it's vibration travelling up a racket into your arm, or shock travelling up your leg with every heel strike — and converts it to heat instead of passing it through.

How it works

Product Highlight

ShockSorb® Dampener V3 Ultrasoft

ShockSorb® Dampener V3 Ultrasoft

1

Vibration intensity dampening

Sorbothane absorbs up to 94.7% of impact shock, converting it to heat rather than sending it into your arm. No other dampener comes close.

2

Vibration frequency tuning

Shifts vibration out of harmful frequency bands without muting feel. Two profiles, two distinct experiences.

The friction inside the shoe, that's the first problem in tennis. It destroys toenails, breaks down your movement, and nobody talks about it. This sock is special. It solves it

“This dampener is a real improvement over the V2, which I already felt was a significant step up from anything else I've used in 15 years of tennis.”

“I do think it helps absorb shock better than conventional dampeners, and I like the sound. Every little bit helps avoid injury.”
