Shoe Dating-Avant Premiere-Made in Italy

They're cute, but I agree not 70s . Avant Première was sold (and maybe still is sold) at the Manor department store chain here in Switzerland - at one point I actually thought that it was kind their own brand becaus they had it in clothes, accessories and more, but I'm not sure. I didn't see this brand at any other store here, maybe they had some special deal with them. Manor is a proper department store that has everything, and they sit sort of on the mid to slightly higher level, but not aspiring to designer brands etc. Their own brand cashmere range used to have a reputation for the best value for money cashmere you could get here. It wasn't super expensive, but for that you got good quality. The store here in Zurich on Bahnhofstrasse closed last year after decades, because the owners of the building went crazy with the rent and now they want to put in all boutiques and offices. Probably more watch boutiques for tourists .
Since I don't really buy new-new clothes anymore, I didn't shop there anymore for clothes or shoes for several years (they were good though for travel accessories, haberdashery stuff and the like!). I had a pair of Avant-Première boots that I bought at Manor in 2002 and wore out during my winter in Montreal in 2005. They were all right, not H&M-plastic-shoes-cheap but also also not super high quality.
I had a pair of retro-looking dark brown t-straps with rounded toe cap around the same time (by a different brand though), but mine had a Cuban heel, not the shape of yours.

 

Hmm... I just realised I thought wrong - I must have bought my T-bars around 2005 or 2006...
