Not for cycling shoes
These are WAY to beefy for most cycling shoes. I feel that way about most superfeet insoles, but these ones in particular. These are designed to fit into workboots. The way superfeet align your foot is to create a very large and solid heel cup. This works OK in most shoe applications, but in low-volume cycling shoes, there is little to no chance of this being a comfortable insole. It will push your heel up too high, and your shoe will not retain your heel as it is designed to.
