So every day I walk 2 km to work, and then 2 km back. You know how when you buy a pair of shoes they start out super comfortable, and then after a few months they feel like walking on flat, bare concrete? Well these ain't those shoes! After 2 years of walking 4 kms darn near every day, these are STILL my most comfortable shoes! Amazingly all that walking wore through the 1" soles, so what's a guy to do? Buy a new pair of Keens, and I actually took my old pair to a shoe repair and got the soles fixed for dirty work. Love these shoes!
