I played with these for the first time yesterday. they were awesome.. they feel like feather and very stable.. toe box is a little tight though..maybe I shouldn't have half-sized down.... I may get my next ones true to my size. I don't think the length of the shoe translates into heel looseness. I think it's just little over-extended in the front and maybe they did it for a reason so my big toe does not get so tight in there...
