I work a 14 hour shift 3 to 5 days a week.  I stand and walk most of that time on hard concrete floors.  My feet were killing me.  I began a quest to find the most comfortable shoe or boot that I could find.  My quest ended when I worn my Rockport Basalt boots for the first time.  They are lightweight and the leather is very supple, they seem to mold to your foot.  They absorb the shock of walking on concrete like no other boot that I have ever owned.  I have a black and a brown pair that I alternate wearing.  I also bought 2 more pairs as a back up.  It always seems that when I really like something, they discontinue it.  The only negative that I have found with these boots is that they don't have the best grip on slippery oily floors at work.  I learned to adjust to that.  It would have been nice if they had added a few speed lace hooks instead of grommets all the way up.  The bottom line with me is comfort and the Basalt is the king of comfort.
