Rocker Noel Gallagher began collecting pairs of sneakers when he gave up drugs because he needed to "obsess about something".

The former Oasis star famously blew an estimated $1.6 million (£1 million) on illegal substances during the band's 1990s heyday, but he turned his back on his bad habits in 1998.

Gallagher admits he was left with a gap in his life, so he decided to start collecting footwear by sports brand Adidas.

He tells Britain's Independent on Sunday, "When I gave up drugs I had to obsess about something, and I'm not into cars, not into jewellery and all that kind of thing, and I had loads of guitars, so I set off on a quest to collect Adidas trainers (sneakers). I had silly amounts - you couldn't open a cupboard without 20 pairs of Adidas trainers falling out."

Gallagher owned more than 100 pairs, but eventually decided to scale back on his collection: "I kept the best ones back, I've probably got about 20 or 30 real vintage pairs, and I put the rest back out there - I gave them to charity shops. Funnily enough when I go to Camden market (in London) I still see some of my pairs there and I've been very tempted to buy them back."

The star teamed up with the company in 2011 to release his own footwear range.
