The inov-8 Roclite 390 GTX weighs 912g (pair, size 11); up to size 14; Gore-Tex XCR waterproof lining; durable rubber rand; well-cushioned; ultra- grippy sole; more supportive heel and ankle design than previously; a perfect super-light boot for the fells. But still not as supportive as other boots, so best restricted to grass and easier terrain; not as durable as heavier leather boots.
