Great socks

Just what I was looking forward to receiving - very comfortable, soft, up to the knee socks - perfect. A little hiccup with delivery but smoothed out very quickly - thankyou Seasalt!

Great socks

These are really comfortable to wear. I take a size 41 shoe and these are long enough and stay well in place. I bought 3×2 and then bought more, enough to keep me and my daughter, who frequently 'borrows 'my socks, going for a long time!

Lovely and long

I bought a pair of these socks a month or so ago and then purchased another in the other colourway. Being tall and taking size 8 shoes, I find it difficult to find long socks which are actually long enough. These are brilliant and fit so well. I also like the fact that they are made from organic cotton. Thank you Seasalt.

Fab Socks

OMG I have been waiting for these socks for so long. I used to wear the long stripey sailor socks years ago, then Seasalt stopped doing them or anything like them. It is really hard to find comfortable long socks so I have bought 7 pairs already!

Love these

Really like the soft cotton and the stripy blue colour, which adds some interest without being either too eccentric or too dull : )
Nice comfortable tops which stay up but don't cling too much.

Comfy socks

I really love these socks. The cotton keeps your feet warm but also fresh. I prefer a longer length sock but have found them difficult to source in the past - this will be a problem no longer - more designs please!

Huge high mast socks

These socks are significantly larger than Seasalt’s shorter socks, so do not buy unless you are at least size 7-8. Fortunately I could see they would swamp my size 5 feet before I opened the packaging so was able to get a refund easily. The staff in the branch shared my astonishment at the size too.

Hi JudyB

Thanks for your review and feedback for the High Mast Socks.

These socks are for size 3 to 8, but we're sorry the size wasn't perfect for you at this time, and we'll pass your feedback to the relevant team for their consideration

Best wishes

warm socks

Nice comfy socks, length is below knee. Nice and warm for cold weather. I wear under trousers on cooler days.
