I have 7 pairs of shoes & sneakers and all fit equally on both feet. Read reviews saying the Seavees ran small, so I ordered a half size larger. Left shoe fits fine, the right shoe seems 1\2 size too small. In addition, there is a glue ring on both shoes, just above the rubber band, which runs above the sole. Very sloppy workmanship. Nice sneakers spoiled by poor quality control.
