pia wallen toddler slippers. The same insulating features that keep sheep warm can keep your childrens feet warm in Pia Wallens 100% wool felt slippers. Soft yet rigid enough to be easily slipped on, the slippers also have a rubberized bottom to make their steps more stable. Swedish designer Pia Wallen spent the past twenty years perfecting her work in felted wool with a line of slippers, handbags, blankets, storage boxes and even jewelry. Like many designers from Scandinavian countries, she uses bright colors and contrasting stitching to infuse home and fashion design with a lightness during the darker winter months. Her work is included in the permanent collections of design museums throughout Europe.
