I only wear them indoors mainly on carpet. I prefer these ones and my wife prefers the thinner ones from SteelSeries. I?m grateful these worked. Me gustó demaciado, el empaque venía bien cuidado al igual que la fuente, el precio muy accesible, mejor de lo que esperaba. I know the hooks are not even, but I couldn?t straighten the hooks once I placed them on the tile. The keychains are in perfect condition and look amazing! Je m?en sert pour jouer au tennis très léger I?m pretty confident that it will last longWould I recommend this? Yes! Seems strong enough to hold more weight. My daugheter needed these for the house as slippers , she is very pleased with the fit and quality
