Have worn Clarks Natureveldts since I hitchhiked through Great Britain in the early 70's (wearing "Polyveldts.")  Each pair would last me about 4 years, and I always had a pair in each available color --- brown, black and some variation of cordovan.  Why Clarks decided to "evolve" a perfect shoe is beyond me.  Shoe still looks good, but last is clearly different.  Feet have never felt the same.  Now, just an okay shoe.

UPDATE: A couple years later... once broken in, these became my favorite shoes.  Have worn very well, and still look great.  Constantly being asked where I got my shoes.  Now, sorry that Clarks stopped selling the Nubuck Nature Three and wish I'd bought more pairs. Whatever I favor seems to get discontinued./skb
