For the first time i tried to skate a pair of slipon janoski sbs and while i liked the way they feel and respond, they leave me feeling naked around my ankle.
that is something i just can't trust even though i don't tighten my laces at all when wearing shoes that have them.
i can just foresee a blowout and i've heard when that happens you have to wear two pairs of socks, something i aint done since i was broke and 16.
go with a pair of ht janoskis, they last forever or take some time and stitch up the elastic parts of the shoe near the ankle that rip after a few sessions, i think they are the main reason why skating slip on shoes sucks. there's no durability in that region of the shoe since skating isn't taken into consideration when they design them but that's just my guess since most folks don't skate slip on shoes..
