I remember when I first went to the US early '90, and my thoughts were then 'the whole nation is wearing the same footwear'
trainers, they weren't quite as ubiquitous then as they are now here in the UK. I never really liked them, but eventually caved in to wear them beyond the gym, my left leg has some wear and tear around the groin area and I feel I need a shoe with some shock absorber factor come warmer weather I'll be in sliders, I don't like the feeling of my feet being encased, but again I have to shop fairly carefully for those too now it's a drag. I always remember my grandmother and what I considered then 'her little old lady shoes' which no one outside that generation would wear. Not so with trainers, inter generational. Comfort becomes a thing as we age, so I guess that's why Stephen Fry had his Sketchers on.
My husband used to like his smart shoes, and a couple of years ago bought some 'Loakes' which I understand are the business in men's shoes, they remain in the box other than an outing out for one of the granddaughter's wedding, they haven't seen the light of day. Quite uncomfortable he tells me, he prefers well worn deck shoes. One of my sons has to be fairly suited and booted for work, which leads our granddaughter to comment on his 'weird shoes' when he's in work atire, her generation really only know trainers. I do miss the variety of footwear I did wear, and I've still got some of my 'heels' but again they languish in cupboards.
