Indoor use ait fix nursing care shoes, comfortable to wear, black, size M. Please note that this is for the left foot only. - Gait fix - Size: M - Color: Black - Accessories: Storage bag My left foot requires size L due to wearing an orthotic device. My right foot is too big with size L, so I need size M. I always have one of each size left over, so I'm listing this in case there are others in a similar situation. Please let me know if you don't need the included storage bag. Thank you for looking.
