I think David (Great name by-the-way)

That for casual I'd aim for a lightweight boot and hiking sock (Like you can see in Grahams gallery).

At work when you need to be a little smarter try a thinner longer sock sock Try the Bridgedale make .I buy loads when I'm home in the UK they have them in Coolmax, which breathes really well, also they have all different types and colours .

All the best David from David (Freelander)
