The importance of socks !!

[Daithi2004]

..... I've read but never practised putting on one pair on fine socks (More and likely the ones you are wearing) and then a thick woolen pair over the top.

This provides comfort and shouldnt blister aslong as your boots arent too tight.

Yes Oisin, I have been hillwalking for about 25 years or so and have used this method all the time and I have never got a blister. (Tempting fate by saying that) I was told that when you wear the two pairs of sock, it somehow prevents friction thereby preventing blisters. You can go for the cheaper thick woolly sock but I do have used Bridgedale and other brands over the years.

I read all the reviews and opted for the 1000 mile "Heavyweight Walking Sock"

they do shrink a bit when washed, i only really noticed this when i bought a second pair the same size, thats why i was finding them i bit uncomfortable when i first put them on, i should have gone for a bigger size

Yep, stinking smelly socks are a must.

A lot has got to do with the boot, IMO.

Blisters, the way to avoid is good boots and good socks.

I have worn poor boots over runs and used 2 pairs of socks. 2 pairs of socks works

Brasher hillwalker / trekker socks. Can't recommend them highly enough. In millets in cornmarket on a permanent 2-for-1. I have about 12 pairs and wear them every day. Extremely comfortable and not hugely expensive. Wouldn't know what a blister even looks like ;-)

Brasher socks get my vote.
 
Lidl sometimes do walking socks and they're good too.  they do thin summer ones with thicker bits at high wear areas like the heel.
