My old runners are falling apart and I really need to replace them. There aren't any specialist shops open near here, so I don't know what to buy. I can't find the same ones in my size.
They're Brooks Adrenaline GTS women's. They're a neutral shoe and I use orthotics with them.
I'd really prefer to spend £60-£80 - definitely not £100. All the ones on Amazon are £££ for my size. 
Any suggestions please?
