These Cascade Heavy Rib bootights are the best for wearing with dresses, skirts, or underneath pants during cold winter months. I absolutely love the feel of these bootights! They can be worn all day and into the evening for almost any occasion. The feet fit perfectly, and are warm without being too warm or sweating. The legs portion fit snug, stay put, hug my legs, and keep my legs warm. Although I live in California, winters are very cold for me. I wear these bootights often and with most all of my outfits during the winter. They make me feel as if I am wrapped in a snuggly blanket. I wish it could always be winter!
