Don't believe them when they say free returns!
I checked that this was a UK company before I bought - they had a UK address on their website. They offered free returns, so I ordered two pairs of trainers because I wasn't sure which would fit me. They took two weeks to arrive - when I checked the tracking information, they were being shipped from China, which made me worry about the quality of what I had purchased as I have had a bad experience buying from China in the past (which is why I avoid buying from China). To be fair, the trainers that arrived are very comfortable, but now I want to return the pair that doesn't fit me, I find that I will have to pay to return them to Germany - an international shipping fee, which will cost me half of what I paid for the trainers. This is very misleading, but only what I have come to expect from Chinese companies, I'm afraid - they don't care about customer service. If I had known that the returns would not be free (as they promised), I would have only bought one pair.
