Well, Alex, youre really chasing grams at this point, and Im not sure youre going to gain much benefit from it. Your North Face Arnuva 50s ($125; thenorthface.com) actually are quite svelte at 25 ounces. Other trail runners include Salomons new trail-ready XT Wings ($120; salomonsports.com), which weigh 25.5 ounces. Vasque Blur XCR shoes ($110; vasque.com) are 29 ounces. Montrails Hardrocks ($95; montrail.com) are about 31 ounces. And the Asics Trail Gel Sensors ($112; asics.com) are 30 ounces for the pair.
Trail runners tend to out-weigh regular running shoes because they need to provide the extra foot protection and support you need when running on rough, uneven surfaces. So that means trail runners have heavier midsoles than road runners, toe bumpers, thicker outsoles, and other things that add weight.
That said, trail runners such as the Arnuvas or the Salomon XT Wings compete well with road shoes on weight. Asicss excellent Gel 3000s ($117), for instance, come in at 25.1 ounces for a pair, or just a shade heavier than the Arnuvas. Which really kind of surprises me, but there it is.
You might shop around for really light road shoes. Road shoes wouldnt last as long, but if youre on generally decent trails in dry weather, they wouldnt cause you any great harm. After all, youre already abusing your body rather savagely. Try a pair of Nike Zoom Elite 4s ($102; nike.com). Theyre 21.4 ounces for a pair.
