I also use esoles with my Sidi shoes.

I like that I can change the arch supports, which I had to do after using them for 2 yrs., they take up some volume in my shoes and they add more cushioning than the very thin insole in the Sidi shoes.

Esoles sizing also works better for me, specific shoe sizes. They didn't have to be cut to fit my shoes and the arch fits better to my arch unlike some of the other brands that have generic sizing.
