Thanks again Phil but i gave a shop in Fishponds a call today as it was approx. en route for me (pre-empting an extra journey)
Briefly bought a pair of Gandolfi (doesn't sound like like it but actually 'home-made') and though they were a bit flashy - thought they'll suit Dave's ( five live are running a thing where listeners report pretentious people who use the 3rd person) style (usiing the term in the loosest sense) of dancing, perfectly.

Anyhow had to move up 1/2 size but being leather should give a little and upon twisting a little on the carpet, could tell the shop owner was impressed

FINALLY - Kathy (the proprietor) is selling off her - LIMITED (sizes) - stock of adult shoes (ladies' jive and ballroom) and men's (some sneakers? and ballroom?) at
50% discount (mine cost me £35)her no is 0117 9655660 and the shop (Kathy's Dancewear) is in Alexandra Park, a small road left just before GALA bingo and after the Lodge Causeway junction on the main drag thru Fishponds. (she said it was ok to mention her business)
footnote

- the shop's prices seem pretty good when i checked out the Gandolfi web site.
