5 Pair McKesson Gray XXL Non Skid Hospital Travel Slipper Socks Above Ankle Lightweight, Poly / Nylon Knit Outer, Terry Cloth Inner Stretchy construction & Slip-resistant treads Grey color & Latex free Single-Side Tread Socks are slipper socks with non-skid bottoms Tread Socks are the same slippers that are “hospital issue” in many hospitals These are 16 3/4 inches long and the non skid tread is 10 inches long. The last 4 pictures have a tape measure next to the socks so you can judge the size Please don’t go by just the sizing as all the manufactures decide the size of the socks not me and they are all different depending on the manufacturer that’s why I give good pictures with tape measurements so you can be the judge and don’t expect that if your foot is swelled up the size of a football that these will fit as they are not meant to fix or treat medical problems as they are just no skid socks nothing more. And if you have questions about the size please ask before purchasing.
