I've run in Nimbus forever and have no problems and would highly recommend them. They do seem to have a wide toe-box but maybe that would help with your numbness despite you having narrow feet. I wear them half a size larger than my day shoes. They do lace rather tight across the toes and I find elastic laces better than the supplied ones.
Well done for all your walk-plodding Speedy. It sounds as though you are really committed to it.
We're having a bit of a family do today in the form of a garden party / buffet. Currently the wind is howling off the sea at a million miles an hour and I can barely open the back door let alone hang the bunting from the shrubbery!! Where did the beautiful summer go?
I'm 50 and wouldn't want to lose my mum yet, so I'm glad she was in her twenties when she had me and I'm glad I was in my twenties when the limpettes were born. I am looking forward to grandchildren now but I absolutely wouldn't want to start being a parent at my age - I'm knackered enough just looking after myself!
