that is my contribution and, I'm sorry, I don't know anything more:
John Spencer used to be a Northampton manufacturer of mid-price shoes, who went under, maybe in the early 90s.
Last owner of the company was Marks & Spencer (no relations).
The brand (maybe the name only) has survived in Spain, just like 'Lotus', another traditional Northampton manufacturer.
If those John Spencer shoes, made in Spain or further afar, share anything but the name with the former Northampton company,
I wouldn"˜t know.
I bought a pair of cap-toes in Lane Crawford here in HK for a little under $3000HKD. These are my first nice shoes ever for work, so far so good. It's obviously not as good as the bigger names, I had this and a pair from Fratelli Rossetti to choose from and I got these.
I have a pair of there chelsea boots and the skin is of low quality and the fit is bad. I would not recommend them. In this price segment i like Barker or Loake better, but i dont know if thay have a boot in the same style.
