I ordered a size 10 to replace a size 9-10 worn-out slipper. Fit borders on being too snug. I compared measurements -old slipper to new - and was surprised that the Rock Dove slipper measures bigger than old slipper. (I measured sole and toe box, -which is where fit feels too snug.). After measuring, I realized that the almost-too-snug issue with the slipper is due to the generous padding inside the slipper. Ordinarily, the padding would be an enhancement, but here, it affects the overall fit. ISee full review
