How to prevent knee/shin guards slipping? I am using plastic guards that cover knees and shins, like the ones displayed here:



My problem is, when I am riding, they sometimes slip down, reducing protection of my knees. This mostly happens because of vibration, while I am riding down (it's when I need them the most), but sometimes also when I am pedaling up.

If I fall down when my guards have slipped, it's as if I had no protection at all.

I noticed that on some days I get lucky with my straps and they sort of "stick" to my legs and don't move, while on other days I constantly readjust them, and they slip all the time.

How can I fix this problem?

I am willing to buy a different type of guards if that would solve my problem (however, I don't want soft/flexible guards - plastic has better protection).
The top strap should go above your calf muscle, and it should be tight enough to not fall down.  Don't depend on stretchy elastic.

Do they reach down to your instep or do they sort of float?  You might get some benefit by tucking the bottom of the guards into your socks.

Another option is tape - http://www.hockeymonkey.com/hockeytape.html  would do the job.

The only knee guards I wear are sports style tube ones, not armour.  However I do wear thin gloves all rides, and have worn elbow pads in a MTB race.
