These boots replaced a pair of Merrell Tetra-launch boots that I wore for several years (and loved!).  The materials, foot bed, and sole look and feel about the same as the TL-these are just a bit taller.  I was hesitant to purchase at first because I have large calves and tall boots simply do not fit me...ever! The first time I zipped them up they were a bit tight but they quickly stretched. They are now amazingly comfortable.  I bought the brown and the color is beautiful.  Just like the TL they are waterproof and the material (or coating) scuffs fairly easily. Gives the boots character, in my opinion. Overall, comfortable and worth the price.  I am a standard 6.5 and these boots felt true to size.
