If you're looking for a solid birthday present for your Dad that you can give every year, do not buy from Quiet Rebellion. With other sock brands, I could rely on them wearing through within 12 months, meaning I had an easy - but well received - present option every year. This year, for the first time, I was horrified to discover that last year's batch from Quiet Rebellion (the first time I have trialled this new brand) were still in perfect working order, despite having been worn every week. Naturally, I was bitterly disappointed and I had to look for an alternative present, which was a massive effort. It's such a shame that the socks are so robust as I really like the designs. I shall not be making a repeat purchase, unless this company commits to substantially lowering the quality of their socks.
