I'm around 115 lbs and I'm about 5'7 most times wearing a small in dancewear. I was going through my cart before I checked out and made sure everything was a small but made the mistake of getting them too small, this was completely my fault considering footwear and clothing are completely different so considering that, they are true to size, although sizing is different than normal streetwear, I would definitely size up from your normal leotard or dancewear size. Besides my sizing error, they worked perfectly and these were my second pair after owning another pair from about 2 years ago. They did start to tear but definitely worth the price and considering the amount of time I had them. They are extremely durable and comfortable which is just how it was expected. Shipping was extremely quick and costumer service is super helpful and kind when it comes to exchanges and questions. These were great as warm up boots for the studio or to walk from your car to the studio. They Kemp my ankles and feet warm without having to risk the durability. 5 out of 5 would definitely recommend!
