For sale is a pair of Vibram Fivefingers KSO Trek shoes in size 43. These are black and leather. The KSO Trek is a very rare model that is awesome for everyday use! One of, if the last, model new in existence! I am a huge Vibram Fingerfingers enthusiast and have a substantial collection that I curated over many years. I am currently thinning out my collection, so please check my other listings for a large amount of size 44 (or 43 for KSO Trek models) shoes for sale.
