As per the title, these sports socks are quite thick/warm, are very comfortable, wash well and should last for a long time before wearing through. I have bought several pairs over the past two years and worn them all a lot, yet they still keep their colour and shape after washing. The elastic is very good, too - not too loose or tight and not prone to 'snapping' with repeated wear.I have bought various budget brand sports socks over the years and had to throw them out after a couple of washes when they have either stretched, gone bald on the heel or had the elastic in the 'cuff' snap. The Lyle & Scott ones may cost a little more, but the certainly do last well!Recommended.
