The Emu Stinger is every bit the quality of Ugg boots. Materials and workmanship are first rate. The major difference between this boot and the Ugg boot, is that the Ugg boot has a more snug fit in the heel. The Emu boot has a wider fit in the heel, causing some small heel slippage when you walk. My wife wears both and never complains, so it must not be a big issue. Emu prices are more competitive, and as I said before, the quality is first rate. My wife wears a 10 street shoe but wears a 9 in the Emu.
