I bought these boots in the sand color for my son for his birthday.  He normally wears a size 10-1/2 or 11 and I bought size 10.  They fit like a glove.  They didn't require any breaking in period.  Because the sand is such a light color, I sprayed them with the spray I use to coat my Uggs.  It doesn't darken the suede or make it stiff.  It just protects against water and dirt.  I highly recommend these boots.  My son loves them and they look equally good with khakis and jeans.
