Dear Migros
A few months ago I bought the winter M-Budget socks. Even after washing and tumbling them several times, they still fluff up incredibly on my feet.
In and of themselves they are comfortable to wear but when I take the socks off I just have black feet. So the socks were definitely a bad buy. Now I've bought branded socks again because they don't fluff.
Maybe you can test whether it was just me or whether the socks are just not that good.
