I was searching for insoles for my feet for several years. I tried all of the over the counter, less expensive ones. I must have bought 50 different pairs. Nothing helped my feet. I finally got a job that offered FSA benefits, and I was browsing online for places that accepted FSA. Bilt came up and I thought to myself that it couldn't hurt to try them out, since all the others ended up in failure and a ton of foot pain. Yes, they are expensive. Buy multiples. All of your shoes need these. Seriously. Don't try to be that guy who moves his insoles from shoe to shoe. It's not worth it. Just buy more. I ordered 2 everyday and 2 active, the first time. That got me through the first year. That was last year. This year, I got new shoes, and needed new insoles again, since you really don't want to use insoles for longer than a year, anyway. So in January, again, I ordered two more pairs of active insoles.
I work in a demanding job, on my feet and moving, for 13 hours a day. Out of 14 days, I work 10 days. So I'm tough on my shoes and I need insoles that can handle that. The active insoles live up to their expectations and then some.
The foam kit to make the insoles is a little weird to use, but it's honestly worth every icky feeling to get insoles that are this great.
And just in case you care, I'm now ordering my third set, since I broke my newer shoes and need more active insoles. I'm a customer for life - and I can be, since they keep the mold for future use.
