>>772627>Don't they lack proper ankle support though that these other boots provide?Yep, they're just running shoes with more aggressive tread, but the people who recommend them are either kids who haven't accumulated any sports injuries yet, or they stay on groomed trails with light packs, or most likely both, and they don't understand that what works for them in their terrain doesn't necessarily work for everyone else. I wear them as urban walking shoes but I don't like them for hiking. Even for easy day hikes you still get twigs and stuff in your shoes if you go off trail.
They do make high top versions that resemble boots, but I wouldn't get them unless you really need the ventilation, you don't care about waterproofness, and you don't mind replacing them every year. Otherwise properly fitted and broken-in leather boots are much better, and cheaper in the long run.
