The socks are not good at all. Firstly, the design is wrong with the material being too thick and my feet too warm during Pilates classes. Secondly, the size is too big even though I am a s small size and I bought a small size. This is simply because the material is loose and thick so it wont move along with your feet during your feet movement on the ground. so you will suffer when u doing lunges during Pilates or barre. What are you supposed to do with these socks if they cannot function during exercise and have grips on them??!! I bought 3 pairs and the moment I received it I regretted it so much. The full toes socks are nicely designed but not this. Finally, the quality is not good, I have only wore a pair for less than 8times, and the string starts to pull out. I wanted to return it so much but it was on final sale. But i did not know this kind of functional socks can be this badly design from a famous brand. I was gonna leave it but this socks really has issues with its design alone!!!! no wonder it was on sale.
