These are really great- My Dad got frostbite on his feet during Battle of the Bulge. Da hilft es auch nichts, wenn die Schuhe bequemer sind als andere, wenn sie bis zum Himmel stinken. When you unwrap it it does not not become fully flat on the desk. YAY FOR ME! With the heel strap being part of the continuous adjustable length of webbing your entire foot will move as you walk. She can put them on herself. Otherwise you will have the same regrets I have. Also, when these warranties are emailed to you they dont actually tell you what the warranty is for, so I just reply to the email with a label of what I bought it for (like "la crosse alarm clock"). The quality is very very good. , I REALLY FEEL CHEATED.
