Here is something you might be very interested in....
I have a small business manufacturing carbon fiber items for road bikes. One of my latest items addresses the shoe width and fit question directly...
I have been a road rider/amateur racer for many years. Some years ago I developed a hot spot on my right small toe joint on the outside edge of course and since my shoes were near the end of their life anyway I decided to cut open the side of the shoe to remove all tension from the afflicted area.
It was such a relief I went all the way and made a slit all the way around the front of both of my shoes opening up the entire toe box. It was very comforting change!
Fast forward to today.. I now produce an item that makes any shoe the most comfortable fitting shoe that can possibly exist.
It is a Custom, Carbon Fiber, 3-Dimensional insole. It supports the arch like most other insoles do but it goes much further... The 3D insole wraps up around the sides of the foot encasing the foot in a cocoon of perfectly formed Carbon. What this does is it keeps the shoe from compressing all of the bones, ligaments, and nerves in the foot and it also stops the shoe from cutting off circulation. Now the shoe can no longer compress the foot in a horizontal plane and it does the one and only thing a shoe should...hold the foot down without irritation. There are a few more features that make this custom carbon insole even more attractive but I dont want to ramble on here too much since it is a forum and not specifically a sales arena.
