These Bates Delta-8 boots are comfortable and is what I expected them to be.  Wore these in patrol and stuck to this brand since 2003.  This is actually my 7th pair of Bates boots... (5-pairs of Ultra Lites, 1-pair of GTX-8 and finally my newest replacement are these Delta-8's).  Light, breathable, easy to run with and zippers have not failed to date.
