I ordered the boots a 1/2 size small based on feedback from other buyers.  Bad idea.  The boots then came 1/2 size too small.  I wrote a comment to this effect and before I signed off, the seller had offered to mail a replacement pair. I paid some shipping, under $5, and sent back the original pair.  In fact, the seller mailed the replacements before I could even get to the PO!  Great service.  Unfortunately, there are two colors for this boot and they sent me one of each.  I think I can oil them and make them look the same.  Oh, well.  It was still great service.
