Last fall I switched from the Asics Gel-11xx series to the Speedstar IIs, but now they are discontinued. I love the Speedstars, and had no problems when I switched to them except for some small heel pain for the first week and a half or so, then it went away. Would I be safe in switching to the Hyperspeeds for everyday training or would they be too light to switch right away? What about the Banditos or the Adizero CS as a transition between the Speedstars and the Hyperspeeds?
