I purchased my first pair of havaianas flip flops & my son a pair of superdry sliders, think they could be copies, the flip flops thongs were not as they should be and were too big, my sons sliders didn't last that long either, unfortunately I was unable to contact them at the time so ive left it too late to sort it out, due to a grandparent been extremely ill at the time, on reading the reviews on here it doesn't seem like they would have don't anything anyway, I'm so glad they were a reasonable price & wasn't expensive, I was typing out an email to them, but thought I'd check the reviews to see if they could advise on the thong problem but seems pointless now if they don't even get back to people who do it in the 14 day period, I certainly wont be recommending them to anybody that's for sure.
