Alunda Hybrid is a sleek, timeless hybrid boot from Tretorn that encompasses all the features you need. Alunda Hybrid is the shoe that keeps you warm and stylish in cold and rainy weather, thanks to its warming, recycled winter lining and an exterior made up of three separate neoprene sections that create a refined silhouette. The sole is made of natural rubber. Alunda Hybrid is simply the perfect hybrid boot for those who don't want to compromise on style and functionality for the fall and winter seasons. The Alunda Hybrid runs small, we recommend going up a size.
