Sometimes little feet need a bit more warmth than an additional sock. These fleece liners will keep toes toasty all year long. They can be used with MyMayu boots to layer up or down, making our boots suitable for most any weather conditions.

Constructed of dual sided, 100% polyester anti-pill fleece, the Helios Liner is specially designed to fit perfectly in Muddy Munchkins, Explorer or Play boots so the liners stay clean and dry. The seams have been strategically placed for maximum comfort. Seams are located on the outside and in specific places to minimize irritation to little ankles and toes. They fit snugly so they don't bunch up in the boots and have a slight stretch for comfort and to accommodate all kids, whatever their calf size. Helios liners are made in 8 sizes for little kids aged approximately 9 months to 10 years.
