Four months in the finding and several, well more than several and not all Tri Shoes either, pairs tried and returned I have finally found a pair of Glass Slipper Tri shoes that fit; Time Ulteam Tri Carbon
Those that did not make the cut:
Bont; A Three, Sub 9 – both had heel slip and tight on toes
Louis Garneau; Tri Speed, HRS– heel slip on both
Sidi; T2 and T2.6 – tight toes
Shimano; T31 – too tight over foot, T600 too expensive
Giro; Trans, Apeckx – Trans was close but not right enough
Mavic, Huez, Pro, Galibier, Zxellium, Avenir – heel slip in all of them!
Lke CX311C – too narrow
Now I just need to perfect that flying transition to avoid scuffing all that lovely carbon fiber!
