Can I glue some soles to my sidi winter road shoes?
 

I use an SPD cleat and I do a bit of walking and standing. I use mountain bike shoes for my summer riding, but I have the Sidi road winter shoe.

Can I bolt or glue a sole onto this shoe? To create a flat area to stand on and to add a recessed location for the cleat?

I'm asking in this forum because they are road shoes.

I am not concerned about the flex. The most walking I will do is into a store or up to the office.

You might have some luck visiting an experienced cobbler/resoler. For example; http://www.davepagecobbler.com/

He does a lot of work with rock climbing shoes, hiking/mountaineering boots, and ski touring boots, but he might have some ideas.
