Ugg Lyla knit - first that this brand launches with a metallic knit shaft. The entire base to the ankle is made of black suede with a slight shiny finishing in silver reflections. But this is special suede! It is UGGPure twin-face sheepskin, which means that the suede outside and the wool that covers the interior are naturally joined together, thus being part of the same piece, without seams or glues. As you can see, it is best quality leather and its malleability and resistance are guaranteed. One very important detail is that the heel is reinforced in order to prevent it from deforming with time. Because of that, it allows to walk with security and stability. On the other hand, the shaft is composed of wool threads, alternating between black and silver. It also has small sequins that give it a special shine according with what the light gives them. The interior of the shaft is made of a thin fabric, while the base is made of soft and cozy wool. This wool keeps your feet at the right temperature and is breathable. The sole of the Ugg Charcoal is made of EVA foam, very resistant and flexible. It is patented by the brand and, in addition of being lightweight, it cushions impact really well. Thus, you will feel rested even after a busy day. Use these Lyla boots for your day-to-day either with tight pants or leggings, so that the shaft stays visible. Great Condition.
