Review: È un tutore per chi ha grossi problemi soprattutto ai legamenti. Il ginocchio rimane decisamente stabile ma è molto pesante ed impegnativo da portare. Fa il suo lavoro ma lo consiglio solo se avete dei problemi seri, altrimenti diventa difficile da portare
Review: I have a full ACL rupture in my left knee. This brace is fantastic - has cross straps above and below the kneecap for ligament support and metal lever that prevents hyperextention. I used it on my 10 day ski holiday and it is comfortable (worn whole day) and sturdy. Fell several times on the slope and brace gave me peace of mind. Just worth noting that at the point when I went skiing my injury was around 7 months old, had 2 months of physio in the run up to skiing, am relatively sporty 27 year old female and was waiting for my ACL reconstruction surgery. Having a brace reduces risk of further injury (at least reminds you not to do stupid things on the slopes). Overall well worth the money and I was very glad not to have cancelled my ski holiday.

## Features

- SUPPORT – Geared side hinges (on both sides of the knee) adds tremendous stability while keeping free movement. Open 360 padded buttress isolates and supports the patella.
- COMPRESSION - Elastic crossing straps for enhanced rotational and collateral ligament support. Increases blood flow and pain recovery.
- ADJUSTABLE - Top and bottom straps assure a personalized fit. It allows for adjustments throughout the day or during activity.
- COMFORTABLE – Fits both left and right knee. Bound edges prevent irritation and skin rubbing. LATEX-FREE Neoprene provides thermal compression to keep your muscles warm and prevents injuries.
- KEEP COOL & DRY- Perforated back panel sleeve provides heat and moisture management and all-around comfort..SIZING - This knee brace is intended to fit snug for the best support. Although, if your measurements are close to the maximum size range, we recommend sizing up for comfort.

## Questions & Answers

**Q: does this pull on or is it open and then strapped on the knee?**
A: The McDavid 429XR Knee Brace pulls on over the knee.

**Q: 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**
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. Good product.

È un tutore per chi ha grossi problemi soprattutto ai legamenti. Il ginocchio rimane decisamente stabile ma è molto pesante ed impegnativo da portare. Fa il suo lavoro ma lo consiglio solo se avete dei problemi seri, altrimenti diventa difficile da portare
