Zappos has them on sale for $65, but no mention of the gaiters: http://www.zappos.com/n/p/p/7175952.html . The have an 800 number-- time to call 'em.
I checked the Timberland web site and they show only the XCR version. Gaiters are mentioned, but nothign specific as to whether they are included with the shoes. Too bad, as an integrated gaiter on a lightweight shoe is a great idea.
I got a pair of the MontBell stretch gaiters and they are perfect with low-top shoes. I wanted them to keep my pants out of the mud more than anything else, but I found they were great for basic splash resistance to the exposed area between cuff and shoe top. Makes you look rather adventurous with your pant legs bloused into your "putees." That and a Tilley will make you a total Chick Magnet :) My 16yo daughter laughs until she cries when I suit up.
