That may help you out of your pickle. It's in the mall in Sungai Buloh which is a bit far out of central KL.
They didn't have a huge range, but did go up to a 9 
.
I am going back on Tuesday to see whether I can get anything suitable for my flippers.
Now, can anybody help me with DDs feet? she takes a two but adults shoes start at a 4. Her only option, and believe me we've trawled The curve and One Utama is a nasty pair of plastic ones. Clarkes can't or won't order her size for me.
All she needs is black leather, either laces or velcro. TBH, at the moment I think she's accept buttons.
