So, I've fallen in love with some trainers. They are half a size too small and I can't find a size larger anywhere (shops or web).

Would I be foolish to buy them? I am truely in love. They are the last pair at my local TKMaxx

Well. Hmm, I know I am a big 5, I occassionally I have to buy a 6.

But if say you never, ever have to buiy the next size up, maybe it would be ok.

Do you ever have to buy the next size up?

Been there, done that. You will wear them 3 times, they will sit in your wardrobe for 3 years because you love them and keep hoping your feet with magically shrink.

Eventually they go on freecycle and you can mourn.

Save the money and 3 years pain

Don't do it.
I bought a pair of boots last year that were just too big they slopped about on my feet, but I loved them SO much I bought them anyway.
Several weeping blisters and a really painful left foot later I have decided to throw them away.
And I hate them now!

Don't do it.

Oh how foolish I have been I did it despite your wonderful advice. My feet are killing me and the trainers are going on ebay. I will never ignore mner advice again.
