I tried on some SWs today - I’m usually a 4 so requested my size. The sandals I tried were way too long - my toes didn’t even reach the stitching. The shop didn’t have a smaller size and the sales assistant couldn’t explain their sizing system to me.
I’ve printed off the SW guide and that says I need a UK 4 but that’s what I was apparently given today 
I can’t remember what was printed on the inside of the shoe, but there was a 5 on the sole.
Any ideas if these were actually a UK4? I want to order some online but can’t be bothered with the faff of returning if they’re not right so I want to be sure.
