I looked forward to these boots arriving from the minute I ordered them. They arrived, I put the left boot on. Perfect. Warm, waterproof and possibly the most comfortable thing ever to grace my foot. I put the right boot on and it felt a bit tight across the ball of my foot. I loved them so I decided to wear them around the house a bit to see if it got any better but after 10 minutes, my right foot was killing me. Upon closer inspection, the shape of the rubber / duck part of the boot where it  jointed the material was actually a slightly different shape on the right boot than it was on the left boot. Due to the slightly different cut it sat on a different part of my foot not allowing the necessary movement and was extremely uncomfortable. It was too uncomfortable to put up with so I had to return them. A shame because if the right boot had been the same as the left boot, they would have been the best boots I'd ever owned.
