Cycling show fit - two insoles ok?

Been looking at cycling shoes and have narrowed it down to shimano tr01 and LG carbon. The shimano’s are a little tight in the afternoon, but seem OK in the morning (I bought a pair of these on sale). Can anyone who has these tell me if they will stretch at all? The LG’s are very wide in the toebox, and I really need to add an extra insole to get them to fit right. But with a flat insole under my superfeet insoles, they fit great. Is it OK to have two insloles. I’ve never done it before, but it seems like it may cause problems.

I’m on my second pair of Carnac’s with the standard insole under my Superfeet. Can’t beat that combination for comfort IMO.

Did you cut the arch of the factory supplied insoles before putting the Superfeet on top?

Nope, just put em in on top. Trimmed the Superfeet to fit length.
