Salvatore Ferragamo Sachie Chukka Boot - Free Shipping | DSW。Pre-owned but in great condition. The outer material is actually NUBUCK not suede and is incredibly soft. The boots are very versatile and are a perfect addition to your rotation. It appears that these boots have been resoled using a very comfortable Vibram Gumlite sole. The soles are in exceptionally good condition. If the uppers look discolored rest assured that they are not, it\'s just that the nubuck makes it difficult to photograph. Every time that the material is touched it makes a mark on the satin like surface similar to how suede reacts.
