These laces are great for runners. The laces that came with my shoes were crazy-long and I was tired of tucking them in. I happened to stumble upon the idea of elastic laces somewhere online and searched Amazon for them. I had previously purchased a running belt/pouch from this company and it is very high quality so I felt confident that this product would be no different. I received the 2-pack of laces and had some trouble threading one of the pairs of laces through the plastic piece that it comes with it to hold them together. I tried to MacGuyver them but ended up kind of destroying them. The company immediately offered to replace them with no questions. How's that for customer service?! Pretty great. About the product itself, they work just as described and make it nice and easy to pull your shoes on/off. Definitely recommend for runners.
