I had Footprint Insoles one time and they lasted me for a good while, I'd say like four months or so. The water injection syringe can be kinda sketchy too. If you're not putting enough force into the insole, water spills everywhere. Other than that, I thought they were good for jumping down stuff. I put them in my thin shoes and they felt pretty good (although part of me felt like it was a placebo effect, but hey, placebo effect is still a noticable effect). I'd say give them a go one time, if you don't like them, then you can be reassured that it's not for you.
