So far as anecdotal (read, 'subjective') assessments of brands go, I've had sole separation occur in pair of Vasque leather boots; I've never had any dramas with Scarpas. However, I still use footwear from both manufacturers: a pair of mid height leather and fabric Vasque 'Mantra' GTX, and a pair of full height leather 'SLs'. I also own and use a pair of mid height Salomon 'X Ultra' GTX boots, and a pair of Kathmandu 'Drysdale' NGX hiking shoes. As my preference nowadays runs to lighter and lower footwear for most activities, the 'Drysdale' and 'X Ultra' gets the most attention with pack loads up to 15kg in Spring, Summer and Autumn conditions. However, once the scales top 15kg out come the 'Mantra' boots. Anything approaching serious Autumn/Winter use in Alpine conditions, and I reach for the 'SLs'.
Composite shoes/boots have come a long way in the past two decades or so, and some sort of 'breathable' liner seems ubiquitous for everything but full leather boots (decent socks can mitigate the extra sweat that 'Proprietry-tex' inners induce in some people). It's also true that you don't have to spend a 'bomb' to purchase something serviceable either. Consequently, it might be that the mid height Salomon 'X Ultra' boot hits the 'sweet-spot' regarding the range of considerations. I love mine.
All the best.
