Timberland Zipable Trail Shoes

I love the design, but am left a bit wanting.   I want them to either zip together, zip to each other or zip with the sole side in or both.  Zip them together with the soles facing each other.   The video has you zip them up and hang off the outside of your pack, so it makes sense to zip the cloth inside, but for storing inside your pack, you'd want the sole (and the dirt) on the inside
They start at $29.99 from Amazon
