I returned size 10.5 for 11. (size 10.5 was glove tight without socks.) I wear them without socks alwayseven when I dress fashionable (business attire). To wear with socks would fit glove tight. Its cool and comfy without socks. If your flamboyant as I then youll manage red shoes &no socks with style. I got this pair in time to climb high in the canopy of the lychee trees to pick the fruit in the backyard in Hawaii. Truly satisfied. Be aware that you are likely to be teased a bit due to the extrāordinārius aspect of wearing red shoes. Hey, the red color is attractive no doubt!
