I bought these online and they turned out to be the wrong size (too small) as they are sized differently than the KSO model that I had first. They are sized like the Classic/Sprint in terms of which size corresponds to which length of foot. So...I ordered the right size and decided I would try and put the too-small pair up for sale here rather than send them back. These are gray neoprene, above-ankle height, and are good for weather that is too chilly for the lighter VFFs. I am selling them for what I paid, plus shipping. If anyone is interested, let me know!
