Run Wales - I hear what you are saying, but I had my gait checked out 18 months ago at a reputable running shop during a previous calf/shin issue and even though they could show my right foot was not pronating as much as my left the best shoe option was still the Asics 1100 series.
If they don't fit I can always send them back. Have been suffering from a calf/shin injury since feb which has been a recurring concern in recent years, iv'e spent a few quid going down the physio route with no definite diagnosis. Awaiting x ray results back to hopefully rule out stress fracture. I've run in various versions of the 1100 series so was thinking a move to a different shoe may be a option, clutching at straws maybe, but got to try something.
