Excellent quality and sound construction. Unfortunately, some of the stitching is coming away after only a week of light use, but If they last half as long as my previous Smai shin pads, I'll be happy. I have yet to spar in them but have used them for pad and bag work to break them in, and they are comfortable and don't move around or need readjusting. I have yet to find a pair of shin pads that fit my shins straight out of the bag (I think my legs must be bent, lol), but I find Smai guards the most comfortable, having tried both Twins and Fairtex in the past and these are the better fit for my legs. The instep is just the right length to allow me to throw karate-style round kicks with the ball of the foot while offering more than enough protection for the foot if using the instep (nothing worse than collecting an elbow with your foot...) Overall, they are a great product, only missing the total five-star rating due to the stitching separating so early.
