LongBayMen's Memory Foam Diabetic Slippers Comfy Warm Plush Fleece Arthritis Edema Swollen House Shoes

What are the measurements of this slipper? I need to know if my mother in law's lymphedema feet will fit. I need toe box and length measurements.

Do the soles leave marks on floors, I see they are black?

Are this wide, I tried another brand and they rubbed my father toe,, where toe was put together

Where are these manufactured?
