Thanks for your valueable advice. I only have the chance to try on the 4497 last fitting 5. UK6 is too tight & UK7 is way too loose. Thus, I reckon UK6.5 would be the right size, which incidentally is my usual UK size. However, from info I gathered in this thread, most said that 4444 last was half size bigger than the 4497 last & should size down. Hence, the doubt creeps in. Plus, the pair is a sale item & probably has no return policy.
