These are the shoelaces for the adidas Springblade, a legendary (or perhaps infamous?) shoe. It was a sneaker with a revolutionary sole, but the durability was so poor that the sole would break while the upper and laces remained almost undamaged, forcing me to sadly throw them away. I absolutely loved the unique feel of the shoe, so I kept the shoelaces, carefully storing them. However, since there doesn't seem to be a second release, I'm giving up and listing them for sale. They can be used on general sneakers. The total length is approximately 112mm.
