From the pics it looks like you have an 'Egyptian' foot shape, from my experience Ride and K2 work well and they have very plush liners which I feel allowed a little more lateral give for your foot to expand. Worth trying a few models on if you can find either of those brands.Yeah I accounted for the gap there, I was able to get the ruler under the desk lined up with 0.
I can't get over the fact that it's an 8... 9s absolutely crush the sides of my foot and are ridiculously hard to get my foot into. Instant pain on the sides. I'll give it a shot when I go try on boots next month (local places do not have them out yet)
I at least have a baseline, thank you very much!
