He ended wearing them out at the weekend and gave them a tough road test. He went on a walk, wearing inappropriate footwear but decided to wear his new socks. Apparently, he ended up to his ankles in puddles but his socks kept his feet dry for most of the walk. It was only towards the end that the wet finally began to make it's way through.
He's now said these are too good to wear in his work boots, although that was the intention from the start. Maybe I need to make him lots so they don't feel too special for work. Wherever he wears them, I'm just glad they're appreciated and he's happy with them.
