MacNeil - 7 last
Shelton - 1 last
Quinton - 8 last
The MacNeil and Shelton are 8.5D, as the printable AE size guide recommended, and are a good fit.
The Quinton, (a rubber solder version of the McClain) are 8D and are comfortable now, but it took lots of stretching to get there.
Anyway, there are a nice pair of Fifth Avenues for sale on ebay locally, and they are size 8.5D. Would they be a good fit, based on the above, or should I size down to an 8 and go up in width to E ?
