Silverts Men’s and Women’s Diabetic Gripper Non Skid Hospital Slipper Socks for Seniors - Clothing for Elderly

IS THIS ITEM DURABLE

Will these last at least four months? What does one size mean? I need it for a person who wears size 8? Can you wash?

i own these socks in " xl " size . however i have a size " 15 " man's shoe size ... thus they are not big enough . do these come in "xxl "

is this the price for just one pair of socks or does it come in a pkg of 3-4 pairs?
