These dog booties are all brand new old stock on past models and styles. Each order is for one set of 4 dog booties. These booties will match each other, but will be a random model from our inventory. These may include 100% cordura (equivalent to our modern All-Terrain), hybrid fleece-cordura (equivalent to our modern Dura-Paw), and all fleece (equivalent to our modern Arctic-Fleece) as well as past materials we no longer use such as our various rubberized materials and a variety of colors and materials no longer in production. These do not include Featherlites which are being sold as singles. All sales are final.
