It is necessary to take less on the size? it is need for play football** A: Hello, The sizing chart for this product should be located on the main Amazon product page (top left-hand side of the page; 2nd image down and the fitting instructions are the 3rd image down.) If you measure at a size 16.1417 I would recommend going into the XL size. It is always easier to adjust down to comfort than be left with a brace that is too small to utilize properly. If you encounter sizing issues, please contact our customer service department via email - cs@unitedspb.com or by phone at (800)-233-6956 and we will gladly work with you to make this right! **Q: I am not sure weither i need large or xlarge. it is 17" around knee cap.** A: Get the extra large **Q: I play soccer does this knee brace let you run/move freely? I need something with this support.** A: Yes it does. There is no problem from running with it and it provides excellent support for sideways movements of the knee and forward hyperextensions. Because it is a little bulky, you will not be able to bend/fold the leg completely (so that calf would touch the back of the tight). I've used it to play soccer, bball and skiing.
