I have purchased Desert Boots in the past, but none of them have compared to the quality of THIS Desert Boot.  It's comfortabled, stylish and I just love them.  They were slightly more expensive, but boy, are they worth it! They fit perfectly...so if you wear a men's size 8 and a half, that's what you need to buy.  Again, definitely worth the time and money to find these!
I forgot to mention that these are much less expensive to buy here on Amazon...I saved at least $20.00 on this purchase.  Clark's generally cost at least $100.00.  The other pair I bought was in the past wasn't a Clarks and you could sure tell the difference.  Buy these with confidence!
