Price, Cost and Value all getting mixed up again.
Some things cost more for a number of reasons, quality, performance, weight & label. Some of these matter. As above if your sitting on a very expensive bike then their cost seems smaller. If you paid 200 quid more for the bike and got them for 100 it would seem like a bargain.
If your completely into road riding and race and they are comfy and last well then why not even at 60/year for 5 years it’s not bad value. Get that down to cost per ride and it’s nothing.
People pay 3/4quid to sit on a static bike with chav music blasted at them for an hour. Do that once a week and your up near 150/200 a year easy. Seems much less value than a nice pair of shoes that could last a few years. (Also less than 6 months sky tv, 100 average pints, 30 takeaway curries and many other things that just add up)
