OK how's this for stupid :

Size choices are S/M/L/XL

Then check out the "size chart" and "how to measure" guide. Any mention of the available size choices (S/M/L/XL) in there? No, but they do have standard shoe sizes in the size chart which aren't even an option here.

F#%k I'm so glad to be a bloody kiwi, ha ha ha.... ;)
