People expect too much for $3 [SEP] They arrived from Asia very fast! I actually like these better than the official version because they are much bigger (in surface area)  and the elastic is more stiff (the official ones stretched out really fast). If  you're just looking for simple arch padding and your planter faciitis is not too bad then this is a good, cheap alternative.  I wear it around the house and in my boots when I need some relief for my arch. Don't expect miracles for $3.
