50-80 ! That's ultra mileage. I think our 15 a week is probably over the average mileage for the more sane runners among us!

My point exactly. And neither of us use expensive socks thereby answering the OP, Running socks, important.

Just to add to my previous post(s)... On 30-40miles I wouldn't feel confident using normal sports socks, but cheap running socks that have varying levels of elasticity (so they fit snugly to the entire foot) do me fine. Running socks are well worth having if you run a lot, and they don't need to cost the earth!
