I am trying and failing to purchase new walking shoes. The challenge in doing this is that my existing walking shoes, which have now seen better days, are the platonic ideal of what I want and everything else is Wrong in comparison. I would just buy the old ones again, but since I bought them in 2009 even the internet is failing to deliver. They have been replaced by the manufacturer with two slightly different pairs, neither of which is quite right.
Ironically, after ranting about both Marks and Spencer and women's trousers, I appear to have purchased three pairs of trousers from Marks and Spencer. I feel my point still holds, in that I was not able to purchase the socks I went in for.
