PRO: I have owned 8-9 pair of the BOA NF shoes. Hate tying shoe strings. Yes I have had two the the 9 pair fail after several years of use and NF has warrantied them by giving me a full refund. These shoes are great for traveling through airports (easy on and off). The darker colors blend great with casual jean dress for traveling. I just ordered (2) pair of the Hedgehog GTX Boa III as NF currently is not making this shoe.
CON: They are NOT for extreme rock or trail use as the rear BOA knob does get hit and will pop loose. However for normal hiking, crossing water trails and etc they are great.
