As a marathon runner, and when I was an undergrad, I blogged about running shoes, so I bought and was gifted many shoes and gear. I need to declutter, especially duplicates. If you have questions, please put them in the comment section, and I will answer. These shoes have never been worn, but no box or tags exist. The shoes are in great shape, which may seem unnecessary to say, but sometimes new is not always great. The shoes have been in a closet so no sun fading. Search DD8337-400 , and you will get numerous results with "official" descriptions.
