There are several reasons top professionals around the world choose TRUsox as their performance sock. Not only is TRUsox the only sock that can use our patented Internal and External grip solution, it is the only sock that uses our premium wet-grip technology. As you sweat or play in wet conditions, the fibrous material expands, increasing the surface area, providing the ultimate grip. What happens to silicone when wet? It becomes slippery. When it comes to performance, there is only one TRU solution - TRUsox.
