A friend gave me a heads-up about a brand of shoes that I needed to be aware of. T. and F. Slack. After doing the research they are a class act. Handmade to your very specifications down to the colour, they have spawned some modern classic, and as investment shoes go, these are definitely ones to watch!
Looking into the growing trend in coloured soles as an expression of personality, in addition to/instead of socks - there is certainly a lot to inspire your coloured soles whether street or smart!
