Please see photos for any signs of wear, flaws & measurements. The veey back of the left shoe was slightly compressed when stored, see photos. The exterior material nubuck/suede/leather. The interior is lined with Smart Wool for warmth. The adjustment for snugness is a bungee elastic cord. Note that these are great active casual shoes that will take you from errands around town to a hike in the woods this fall and winter. The SmartWool feature allows these shoes to be worn year round!
