Hilarious! Those are the most hideously overpriced socks ever, even more overpriced than the £600 tweed ones my ex-boss once bought to go shooting in.
DS1 spent an eyewatering amount on a Balenciaga sweatshirt type top that shrunk to half size when washed on a cold woollens, so they'll be single wear socks as well.
Balenciaga makes Primark look like quality!
A friend of mine bought some Balenciaga slides and was left with massive blisters where they rubbed so much. They looked like they came from a market stall but were £250! The material was really rough and plasticky. I'd rather wear £5 ones from Primark.
The shoes in the OP look like something that an Olympic sprinter would wear because they're scientifically designed. Either that or shoes that are on prescription to correct posture.
