These are great heavy duty trail shoes.  The tread is agressive and the sole is rigid enough to not deform when walking on rocks.  The only thing to be aware of with these shoes is that the laces are too short if you plan to use all the eyelets.  I solved this by replacing them with much longer laces.  I tried to live with the short laces they came with and had to unlace them a bit each time to take them off, much easier with the longer laces.  Also, the laces they come with are black with some grey, when I replaced I used just black laces; I like the look with the plain black laces better.  The shoes are a little loud as they have some silver in them and the plain black laces calm them down some.
