One of our original styles, the Erin wraps baby's feet in the softness of wool and suede. Wool is naturally heat regulating, so this bootie will warm little ones in cold weather and wick excess moisture in warmer conditions. Plus, its simple hook-and-loop closure takes some of the fuss out of getting dressed. Suede Adjustable hook-and-loop closure Sheepskin lining UGGpure™ wool insole Suede outsole 3.25" shaft height
