Just to warn against the 'work socks' from Matalan; from a pack of five pairs, all holed above the heel after what seems like less than 6 months only worn weekdays (safety boots,flt driver).
Contrast with previous lot from Poundland (£1/pair) which seemed to last for years.
Bridgedale socks. Spend a lot of time on my feet at work(Postie) and I’ve got asstd bridgedale socks for different times of the year (hot and cold). At least 1 pair is 20 yrs old and looks like they’ll last another 20. Washed without fabric conditioner and never tumble dried. Ok, they aren’t cheap but value for money is outstanding.
