Actually a comfortable and fun flex binding from B. Yeah though, don't forget they don't fit dual boa, wing hits the dial.
Wings are useless. I didn't even notice them aside from them hitting my dial.
Advise though, look somewhere else unless you're getting a good deal. Better bindings can be had for less. Check Formulas, Forces, Deltas, or 390's. The Formulas (09/10) are probably the closest in feel. For 10/11, you might like the Hurrithanes, the Formulas are stiffer for 10/11.
Go ahead, drink that kool-aid.
