A waffle sole is a type of shoe sole characterized by its unique pattern of raised squares or rectangles, resembling a waffle. This design provides excellent traction and grip, making it popular in athletic and casual footwear. The pattern helps to channel water and debris away from the sole, enhancing stability on various surfaces. Originally popularized by Nike in the 1970s, the waffle sole has become a staple in sneaker design. Its lightweight construction and flexibility contribute to comfort, making it suitable for running and everyday wear. Many brands continue to incorporate this design for its functional benefits and aesthetic appeal.
