In terms of the support it provides to the foot, it is an excellent product. Sturdy and with quality construction. However, it puts excessive pressure on the quadriceps, to the point of discomfort within a short time of wearing it. And this is despite being purchased in the correct (theoretically and according to the company's methodology) size and wearing it with the straps fully relaxed—almost unbuttoned. Also, under the same conditions (fully relaxed), it excessively restricts the range of motion of the knee.

Very nice. It fits very well on the foot, it doesn't slip and it provides effective support to the knee. The negatives are that it is quite bulky and in the summer it is very hot.

I used them for agricultural work and they keep my knees and joints stable. They don't slip at all, so there's no need to constantly adjust them, and so far they seem quite durable. Also, my legs don't sweat, but it's a bit difficult to take them off. I hope they withstand the test of time.

Very good application.
It keeps the knee stable and doesn't bother at all when you wear it. Simply perfect for its price, it's worth it
