Just as an aside, my feet are now half a size bigger than they used to be, and the arch *seems* to be slowly collapsing. Probably an effect of more weight, more age and less training. I suspect my feet will eventually be a whole size bigger…….
If your feet are getting bigger, your shoes will be getting tighter. And you’ll get cold feet.
Which is why i stopped mucking around with overshoes. No problem with winter boots being 10 times the price when overshoes have so little effect (virtually none)
On the other hand, it gets properly cold here.
