I've skated two pairs of Janoskis and they were one of the best shoes I have ever had. Super comfy but there are a lot more comfy shoes for skating rather than just casual wear so I'd go with the stage 4's too if you're skating them.
I end up destroying a pair of shoes in about 2 weeks at most, but I still go for as thin a shoe as possible. I like the Addidas that look a little like an indoor soccer shoe, but my favorites are the Gravis 'Dylan Wing-Tip.'
no matter how much they may be labelled as a "poser" company or whatever shit that dumb kids come up with these days, DC makes some of the most durable skate shoes I've ever seen. however, the best choice I made was skating a pair of Adidas Sambas. I'm notorious for ripping through skate shoes faster than anybody else in my little crew, and my Sambas lasted me months and months of aggressively skating them.
I've owned Vans and currently have Janoskis. I will probably never skate in another shoe, they're both really similar in grip/durability. I love the vulcanized soles on the Janoski, and the Vans I've owned, but that's just the feel I like when I skate. The Janoski is the comfiest, sickest looking shoe I've ever owned, and I prefer them over vans purely because I love the way they look.
