None of my shoes are comfortable

[Comfy]

Sigh.
I think I am between sizes or something. Five and a half is too small and sixes often chafe from my heels slipping out the shoe/boot. heel grips seem useless, they just attach themselves to sock and tights and roll themselves up.
Plus my arches ache often now.
I got some arch support things from Boots for £9.99 and they help but is there anything else around that might help.
My shoes are all oldish too. Does that affect the support and how can I keep wearing beloved footwear?
I'm not ready to get expanding old lady shoes yet.

have you tried clarks? i have bought a few pairs lately and they are the most comfortable shoes and boots ever, i'm a 6.5

Haven't had clarks for a while. Can't really afford new shoes atm.
Am looking forward to summer as my Birkenstocks are comfortable

they have some really good designs atm and in the sale i found some shoes for £16 that i'd spent £50 on! worth a look instore
