Im 5'10" tall and I weigh 110 pounds and im still growing, my docter says i may be around 6 ft tall when im done growing because im only 16 years old which size should i get? a small might be too short but a medium might not be tight on my legs because my legs are a little small around
Definitely small. They will not compress enough if you get a size medium.
Getting a small pro tight is a great option for you. Being 5'10 you may have a small gap between the bottom of the tight and your ankle. But that is perfectly OK. The support web in the Pro tight gives the best support out of all the CW-X tights for smaller legs. YOu will love them.
