You might be playing on a dirty court, or the soles of your shoes might need a good wiping down. Foamposites have pretty decent traction, from my experience. However, they're a little too heavy to play in for extended periods of time, if you ask me.
Still being patient with the Volt pair, cuz that 200 is kinda hard to swallow. I think they made fewer size 13's, though (which doesn't really make sense to me, seeing as these are a basketball shoe), so I might just have to bite the bullet before they're all gone.
