does this pull on or is it open and then strapped on the knee?

The McDavid 429XR Knee Brace pulls on over the knee.

what size to choose if my size 16,1417 in. It is necessary to take less on the size? it is need for play football

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!

I play soccer does this knee brace let you run/move freely? I need something with this support.

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. Good product.
