Okabashi Foot therapy Reflexology Slide. LARGE The Okabashi website states a Large is womens 9.5 - 10.5, BUT based on how these fit me [I am a 9.5 B], I'm saying they are a 9.5 - 10 One of the photos shows the measurement. I DO NOT THINK this shoe would work for someone 10.5 I purchased new, have never worn, but there are no tags and the close up photo of Right strap shows subtle pink stain” I am selling as I have a used Okabashi that works well for me and don't need extras.
