Clarks sandals are not a guide for comfort, sadly, as I found when I bought "comfortable" sandals when I was pregnant and they rubbed my feet to bits, and the last cloddhopping Clarks version of DMs a few years ago which were not comfy at all. However I got some orange espadrilles from them this year and they are so comfortable and I get lots of compliments.
IMO I'm 49 and tend to find 60+ women and Gen Y women more likely to wear dainty heels and uncomfortable footwear. Gen X and Zs wear comfy clumpy shoes like platforms, wedges and flats, - perhaps a nod to a kitten heel every now and then. We've never really got on with proper heels.
