Any question answered...

Specialized do some good quality footbeds, which are worth the money. They are a fair bit cheaper than the Sidas ones and, having both, as good.

+1 I have Spesh insoles in my Sidi Ergo II's.

With regards to your point Rogan I find that the Spesh 44 insole fits perfectly inside the 45 Sidi- they don't fit in my 44 Sidi Dragons.

that you very much the pair of you!
