I recently came across these in my ongoing search for good moderately priced insoles. When searching for insoles there are certain brands that always pop up first. They are often expensive and have all kinds of unnecessary "features". I have narrow feet and few shoes made today offer narrow sizes so I usually make adjustments with insoles. To this point though, I haven't found anything that I'm completely satisfied with. I've noticed that in Merrell's shoes, I usually do not replace the insoles because they are comfortable as sold. So I wondered if they made just the insoles. Sure enough they do. I tried these and the Ortholite version and prefer these. They offer just enough support without be squishy or having too much arch support. The price is great and having the different thickness options is awesome. Merrell also shipped these very fast. I see myself placing Merrell insoles in more of my shoes from now on.
