I wear go walk and go walk 2, and always buy size 8.5 (26.5cm), this time I still buy size 8.5(26.5cm) for go walk 3, but  WTF.<br />They changed the size. it was too long.  I can put one finger between my heel and shoe easily.<br />so, it was totally un-wearable.  when I ware it and walk, my heel keep  dropping out of the shoe.<br />are you kidding me?  why same band, same go walk series, same size comes different length inside?
