Something I love about Paris which I think the UK lacks is independent retailers, particularly in the concept store stream. In the heart of St Germain is a hidden gem - Le 8, Rive Gauche - only having opened about 4 months ago, it is new to the Parisian trainer scene. It is a concept store with the tag-line 'Rare Sneakers and Fine Apparel' and both of which, it definitely has. Whether you are after Nike Barkleys, Jordan Originals, Air Max or Adidas, they have it and they are amongst a huge collection.
Every month the walls are showcase to a different artists work (which opens with a champagne soiree), the rails to a small collection of one-off clothing from a different designer and the cabinets full to bursting with restored trainers, rare finds and unusual styles.
Their website is currently under construction, but if you are in the area and into trainers, it is definitely worth a look.
