This model shoes 1 size smaller and suitable for the purpose as the foot sole with arch Adiprene (super comfortable) takes up space. Trusting the advice, I had bought a 36.5 and 37.5 c footwear usually was really too small. I bought a 38.5 and it's perfect. Very stable with their non-slip soles and sole Adiprene makes us forget the height of these shoes. Purple is rather gray -mauve marrying easily with gray, navy blue, black
