I use Lake extra wide Mtb shoes. I know the insoles that come with them aren't very good. I tried the red Bontranger insoles, but they're 4-5mm narrower than the Lake's (in the front), so I end up with sores on the outer balls of my feet. Any insoles out there that are wide enough for the Lake shoes?

I like cork Footbeds, they are firm with just enough give to not be bruising, and not unusually fit altering thick.
Been looking at getting SOLE insoles - cork and come in a variety of Types and also widths - they have specs on their site.
Will prolly order for a new pair of cycling shoes...

I would go with Superfeet, I use them in almost all of my shoes now. I don't know how wide their Hockey insoles are (which are basically what they are using for Cycling now) but I know they do some in wide widths (at least the green but I think they did others) They also partner with some other shops to offer custom insoles so that could help (though I am unsure on pricing as I am not set up for that)

I use the Sole wide with my 13 wide regular shoes. I don't use insoles anymore in my cycling shoes as the need seems to have disappeared. Weird, I know. They take up all the room and then some in my Avia shoes. Had to narrow them in the forefoot to fit correctly.
