Nobody writes about socks, which is odd, because they are the garment most likely to fail in any given year and the one where the failure is most annoying. We wore forty pairs across five months, from £1.20 to £22 each, washed them all the same way, and recorded every hole. Fourteen pairs developed one.
The heel and toe reinforcement
One detail predicted almost every failure: whether the heel and toe were knitted with a reinforcing yarn. Of the fourteen pairs that developed holes, thirteen had no reinforcement. Of the twenty-six that survived, twenty-two did. It is visible from the inside as a denser, often slightly different-coloured area, and it takes two seconds to check.
Cuff elastic is the second failure mode and the one people notice first. Of the twenty-six survivors, four had lost enough elastic recovery by month five to slide down in a boot, which makes a technically intact sock useless. Ribbed cuffs deeper than about four centimetres held up markedly better than short ones.
Fibre mattered less than expected. Merino, cotton and blends all performed well when reinforced and all failed when not. What merino did buy was odour resistance and warmth-to-weight, which is worth real money if you are wearing boots daily, and nothing at all if you are not.
“A sock is a wear-part. Buy them in one colour, buy them reinforced, and stop thinking about it.”

The strategy that works
Buy one colour in bulk. It sounds joyless and it eliminates the single largest source of sock loss, which is not the washing machine but the failure to find a match. Two people on staff have run this system for years and both report roughly halving what they spend, purely by not discarding odd survivors.
Darning is worth ten minutes if the sock is decent. A reinforced merino sock with a single toe hole takes about eight minutes to repair with a needle and matching yarn, and the repair lasts. Below about £6 a pair it is not worth the time, which is a reasonable way to decide what to buy in the first place.
Why the drawer matters
The single biggest cause of sock loss is not the washing machine and not wear. It is the accumulation of unmatched survivors — one of a pair fails, the other is kept, and eventually a drawer contains fifteen odd socks that are individually fine and collectively useless. Every person we spoke to who had solved this had solved it the same way, by owning fewer designs in greater numbers.
It also changes the economics of repair. A hole in one sock of a unique pair is a decision about whether the pair is worth saving. A hole in one sock from a batch of ten identical ones is trivial: darn it or discard it, and the remaining nine are unaffected. Standardising is the boring answer to a boring problem, and it is the only one that survives contact with actual laundry.
One genuine surprise from five months of this: merino did not smell. We tested this less rigorously than we should have, but the pattern was consistent enough to report — the merino-blend pairs were comfortably wearable for two days where the cotton ones were not. For anybody who travels, that single property is worth more than the price difference several times over.
Our best value pick was a five-pack of reinforced merino-blend crews at £6.40 a pair. Nothing in the test at three times that price outperformed it on any measure we could record.
