I have several pairs of sheepskin boots: one Uggs Classic Tall, one Ulu Portillo, one Ulu leather outer with sheepskin inner, and these Emus...we need the warmth for northern Vermont winters.

I agree with one reviewer who mentioned the superior soles and arch support, definitely more than Uggs, but they not quite as comfy as Uggs in the trade-off. I also found that they are fairly true to size after ordering a 9 for my 9.5 foot...hope they'll stretch some and am fairly confident they will. The Emus are also a tad clunkier than Uggs Classics, but for the $68+free shipping I paid for these twin-faced sheepskin boots it was just fine (gotta hit Amazon just so to get the really good deals).

When purchasing Emus, make sure you order a "premium" sheepskin boot or what you get is merino wool.  Merino is fine for warmth, but falls into clumps after some wear as the wool is not actually part of the upper as it is with twin-faced and is separately attached to the outer part of the boot. The regular Emus are fine for a fashion boot, but when looking for durability and long-lasting footwear go premium and spend the extra money.

Very happy with my toasty Emus.
