I have wide boats as well, but my biggest issue is the instep depth - my foot is 4" from sole to the highest point in my foot. This becomes a toe-numbing experience for most shoes, even those labeled as wide.

I pray Clarks, Sketchers (for a casual sneaker), and Doc Martens remain true to size forever. I have a pair of bespoke (I sent in 3d measurements of each foot) Olympic weightlifting shoes made by Powerfirm in Canada years ago, they still fit great but the maker sold his business and the site now sells cheap mass-produced Chinese weightlifting shoes. When those shoes give up the ghost it will probably be easier for me to just take up pilates instead.

The Clarks are as comfy as loose socks. You can't beat them... I just wish they carried more classic styles for the more discriminating satchsquatch like myself...
