Shoetique - great price and fast service.Bought my fitflpos as a second pair as i had bought my first ones over a year ago and they were a little shabby. Brilliant fitflops and I paid a lot less than I did last year. It was free delivery and they arrived about 2 days after I ordered them and well in time for my holidays.Thank you and I will be recommending you to all my friends and will be purchasing from you again and again
