What do the letters in the size mean?

The letters represent width.

For ladies, we stock B, C, M, W
B and M represent a medium or more narrow width
C and W represent a wider width
Australians generally have wider feet than our American cousins, so we choose to stock C or W width when possible.
However, you will find the majority of ladies shoes available on the market today are made to B or M width.

For men, we carry D, M, E, EE, EEE, EW, W
D, M and E represent a more narrow fit
EE, EW and W stand for a wider fit
Occasionally we stock EEE, which is very wide
Just about all our men's footwear is supplied in one of the wider sizes
