With all due respect to Old Oak Man and Keeth, I have a pair of Axess Climbers which don't adjust the height that is traditionally gone by. I am 6'4" and these don't get anywhere near the 2-finger-from-the-knee point. That being said, they are VERY comfortable and have never left me with any soreness after extended periods.
In addition, I can wear lace to toe Hiking style boots (ArbPro Clip'N Step, of course

) with these climbers and have no discomfort.this allows me to do all varied work on the job with good comfort an not feel like I'm sacrificing anything. The boots also give me the option to run a HAAS while wearing Spurs. Game changer there.
That being said, I would either go with any advice that sits well with YOU. That's the most important thing. The fast pace of changing gear can be tough to keep up with these days. I wish you the best of luck and a good purchase.
