What sort of soles are used?
Uggs-N-Rugs have settled on a durable quality, lightweight EVA sole which is then glued, heat activated and attached to the footwear under extreme pressure. About 23 years ago, Uggs-N-Rugs were one of the first sheepskin manufacturers to try side-stitched soles. They spent a great deal of money on the machine and the soles. However, sustained testing of this method for attaching soles showed that they decreased the life of the footwear. Once again, this was due to the sheepskin being a soft leather. What was happening was the lip of the soles (at the side) and the stitching just under the lip, created a sharpish edge. Ongoing walking (thereby flexing the soles repeatedly) meant that this slowly cut into the top quality sheepskin. Eventually the footwear developed horizontal holes at the level of the sole stitching to the point that the sole gave away. So in the end, Uggs-N-Rugs gave up using their expensive sole machine (it’s been sitting gathering dust since then) and have reverted to
