    I only wore these a couple times. The elastic straps wear out immediately. The lower strap causes chafing. I never fell wearing them so I can't attest to their level of protection, but they really don't feel like they offer much. Maybe ok for children's soccer. Not for enduro. I ended up buying a pair of Leatt dual axis knee guards for a decent price which I've been using for a couple years and I am pretty happy with those, although I think I'll probably soon buy a dedicated knee brace. Don't go cheap with protection.

    They have held up well and stay in place throughout the ride. I wear them inside the boot and are comfortable for the ride. Elastic bands are alittle wavy after the season but still stretch well.

    Very disappointed!
    Worse designed knee pads I have ever purchased. I love Alpinestars as a brand, and expected a quality product when I purchased these online, but they're terrible! The straps are very thin and uncomfortable, these pads weigh a ton for some reason, and they do not wrap around to protect the inside of your knee at all (they feel like they are just floating on the front part of your knee). I have found that most other knee pads extend inside your leg a little, and this is very beneficial as it protects them when gripping the bike with your knees.

    Purchase anything else, but dont buy these

    thumbs down
    purchased because of pleasant reviews. but if i wear them for more than like an hour the straps dig into my skin so bad. extremely uncomfortable. i get scabs every time i wear them. but you get what you pay for i guess.

    They work
    These knee guards work but are not very comfortable at least on my legs but this is very subjective as they may fit other peoples legs well.

    Good for the price
    Have used these several times now and at first I had a problem with the right one falling down my leg. I found out that tightening the upper strap too much caused it to push down. Once I left it not so tight, it stayed in placed. These are good.
