They sell Chinese size slides and their size guide is EU/UK/US. It is completely misleading, I wear number 40 -41 and the first time I ordered the 41 as in their website they recommend ordering the largest. 41 ended up small so I returned it and I ordered the 42. So 42 came and it is still small! I measured my foot and it is 255 so according to their guide number 40 should have been just fine. Now I need to return the 42 and order 43 which means 20euro plus to the initial price just to return products that their description on the website is wrong. Of course they denied to send me a prepaid label or refund the postage cost.
