In short, I needed a pair of casual shoes that weren't trainers. To use an American term, I needed a pair of casual sneakers.
Went for K Swiss as I've had Adidas Superstars in the past and found them to be tough on the soles of my feet - I could always seem to feel the ground through them.
These K Swiss shoes are incredibly comfortable - the leather is soft, which gives your foot a nice range of movement and flexibility within the shoe. It's not got the springiest of soles, but unlike the Adidas Superstars, you don't feel the ground through the shoe.
They're also quite smart and you don't look like a chav. I've worn mine with blue jeans, stone coloured combat trousers and shorts when I'm out and about at the shops, park, visiting friends etc. They pretty much go with anything (the ones I bought were the white shoes with the grey to black stripes). Highly recommend.
