This was my first BearPaw purchase. I bought a size 5 in the navy blue color. I've got multiple pairs of Ukala Sydney boots, but they didn't offer a boot in navy like BearPaw. After reading the other reviews, I was unsure about the size so I ordered two different sizes, a 6 and a 5, because of free returns and shipping both ways, and ended up keeping the smaller size. I usually wear a 5.5 in a shoe, but in Ukala boots I always wear a size 5. Well, BearPaw is more like Ukala, and the 5 fit better than the 6. I wear a 6 in UGG, but they fit differently and run small to me. Main difference in the BearPaw boot is that the toe box is about an inch smaller than Ukala boots, so remember that if your foot runs wide. You may need a larger size to accommodate a wider foot. I found the 5M to fit me perfectly. The lining in the BP boot seems a bit thicker than in the Ukala, more like the UGG lining. But it compacts down quickly, so if it's a bit snug at the beginning, it will get roomier after several wearings. Overall, I like this boot.
