I can never wear regular "primatively" laced shoes again!!!
I'm on my 2nd pair of Boa Arnuvas, and first pair of BOA XCR's. I run about 300 miles a month on and off trail, rain or shine, and these shoes are great. Completed a 50K and two marathons this summer. The Arnuva's are extremely light, but sized a bit small (I am a true 10.5 but I wear an 11 in the Arnuva's). I'm also a bigger (180 pounds) runner and the support is more than adequate. I will never run in a pair of non-BOA running shoes again...you can get the perfect tension and never have to re-tie.
