Purchased these boots originally for my son (the outdoor / boy scout / hiker) ... then went camping but my old boots (Vasque Clarion Impact Gore-Tex Hiking Boot ) which were tight even at a size 11 W... (I wear a 10.5 EEE) ... I decided to try these boots HiTec Boots at size 13M... thinking, why not give them a chance... on a weekend camp out in mud, rain and lots of walking (a Mountain Man theme camp out).  The boots fit great... granted a bit long, but the width was just right, I replaced the insole with a pair of Spenco(r) Heavy Duty Insoles... they were comfortable and they kept my feet dry.  So, I did the next logical thing, bought a pair for me, same size, and all...  word of advise, I bought these in 11 W, they were to thin, I then bought size 13M... maybe it was just my feet, but they work for me... with a good insole, and a great lace technique, you have a good boot...  enjoy.
