Struggling with Achilles strain and then calf strain after changing my non running workout routine I thought I'd give these a go. I did a few 10K test runs on the road before wearing them on the Tarawera 21k. The trail was tough with many more hills than I thought there would be and these calf sleeves saved me from pain and injury. Recommended!

These are great. I've tried many and these are my favorites by far! I've had calf strain issues in the past and have been relatively injury free lately, but of course that can't last! Tweaked my right calf and then kept training until it really got my attention. I'd lost my old sleeves so thought I'd give these a shot.Within 24 hrs. (plus a vibrating roller) there was enough relief to know I didn't seriously injure myself, prob 50% better in a day!!With sleeves I've used in the past sometimes the sizing isn't quite right where I measure bigger, but the recommended size doesn't offer enough support?! Or some you can't wear that long because they squeeze like a sausage casing. Some are too scratchy, some are too hot. But these OS1st are just right.I don't really ... MoreThese are great.

But these OS1st are just right.I don't really notice I'm wearing them and kinda nice you can tell what is the back from front. And these are the 1st I've seen that actually offer a "Zone" for the Achilles. Def get 'em you'll be happy!!

We know those who are reading this; that you will try anything to stop the aching in the legs,as I have. The tablets, the silly gimmicks, These sleeves worked for me. They are hard to get on and off. As a result I found I can wear them longer without bad side effects. Even the black marks around my ankles have gone. My long standing(tee hee) knee problem resolved. I think it's worth a try but get the quality of cs6 the cheaper ones cause all sorts of problems, one being they drop in bits very quickly.
