Vionic Gustavo Men's Orthotic Slipper with Removable Insoles

Superior quality. So dressy they look like they can be worn to the office. I can't stop looking down at them!!! Removable insole so I can use my orthotics instead is a bonus. Most shoes I can wear size 11, and these fit great in 11. Though I wear an 11.5 Air Force One Nike because Air Force ones are so narrow, and I go up a half size with AF1, I can go buy more true to size 11 in these. I also got them in 10.5 to try since they were slip on and I'd be barefoot but the 11 works best so pick your average size and they should work fine unless you have a narrow foot then go down to half size is my prediction from my experience.
