I have the exact same experience. Of the C&J shoes I have owned or tried on, most all of them suffer from a low and wide heel area which increases heel slippage. My best-fitting C&J are my Connaughts (236 last), but after 3 years of hard wear they still have som heel slippage in them, countered only by the supreme fit over the forefoot. Carmina Simpson has the same issue. Heel-fit-wise, my Loake Aldwychs are much better by comparison, comparable to my EG Dovers.
