Formthotics Sport Run ShockStop Insoles

The Formthotics Sport Run ShockStop is a high-performance running insole designed to deliver exceptional shock absorption, cushioning and stability for runners training on hard surfaces.

Engineered using a unique ShockStop impact-absorbing layer laminated to the Formthotics Formax thermoformable base, this specialised running insole excels at reducing impact forces and dispersing pressure with every stride. Independent laboratory testing has shown ShockStop to outperform many commonly used materials in impact reduction, making it an excellent choice for runners seeking enhanced comfort and underfoot protection.

By combining maximum shock absorption with the natural functional support system Formthotics are known for, Run ShockStop delivers improved stability, ground feedback and everyday running comfort — whether you’re logging short training runs or tackling long distances.

Formthotics Run ShockStop insoles are suitable for both novice runners and experienced marathoners, particularly those who run frequently on hard concrete or pavement surfaces.
