Input: This model may be ok for sedentary types, but I'm active and get around alot in my job - consistently found these stockings rolled up down by my ankles! Not Good!! Solution: go with the standard compression stocking, 20-30, stock #114622. Excellent support, stays up and gives me what I need. Both pair of these also tore as I struggled to pull them up all the time. Good riddance/bad investment!
Output:
Negative
