Most insoles are available in one arch height. They're soft, so arch height doesn't matter.
We're not like most insoles. We take a different approach.
Having just bought Solomon trail running shoes for an ultra-race coming up, I needed a supportive insole that was slim enough to fit in the shoe, but would support my feet over the 3 days & 300+ miles I'd be racing. So far have only put in 20 or so miles on the insole, but it seems to be exactly what I'm looking for. The measuring guide worked perfectly as well. Will use tread labs again for sure.
It's been several weeks since I've been using Tread Labs insoles. I wish I had these insole/arch supports decades ago. They are easy to trim to size, just use the OEM insole as a pattern. I visited the store so I was able to try several arch heights, settled on the #3 height. No break-in was needed. My feet, legs, and back feel great now with Tread Labs arch supports.
These insoles are of very good quality compared to other brands I have used. They also provide a very good arch support, and my feet are comfortable in the boots I am wearing this winter. I purchased the dress ones which are thinner than the sport ones, and they fit into most of my shoes which is a plus. I do recommend these insoles!!!
I got the Stride Thin Insoles and they work very well for me and are comfortable on my feet.
