I ordered a pair of Sealskinz Halo overshoes in size L which should be correct for my size 9 shoes. I then saw a review on YouTube which showed that they would be too small. I immediately contacted Sportpursuit and requested that the size be changed to XL. I was informed that this was not possible even though the order was placed less than 30 min. earlier When the overshoes arrived they were much too small just like the ones in the video. Now I am expected to pay £3.50 to return them. This is not acceptable A) because the sizing guide is grossly incorrect. B) because I attempted to edit my order within the 30 minute timescale required on the website instructions. All I want is a pair of overshoes which fit or my money back without deductions.
