Meet the UGG Lo Pro Button, a summery new UGG that is a little bit lighter than its fully sheepskin lined counterparts. It has a light and breathable cotton jersey knit material on the upper and a sheepskin sock liner on the bottom to keep feet cozy, but never ever sweaty. Sheepskin is a natural fibre that wicks away moisture from your tootises, so fear not, you don't have to give up UGGs for the summer. Another fancy little feature about this newcomer is if you decide to unbutton the boot and fold it over there is a nice pink striped pattern on the inside. Oo la la.
