New to running

Interesting!

My shoes are seriously worn on the outside of the heel, which I understand is a sign of supination.

It usually is - but an overpronator can also wear the outside of the heel, before rolling inwards across the arch to the inner forefoot. (Not doubting your self-analysis, just giving you more info)

I'm only throwing all of this at you because even at the best shoe stores you can get some sales people with really limited knowledge. If you end up with a guy with neutral feet who's superfast and races nothing longer than a 5K, you may have to ask a lot of questions to get what you need! Same as buying a bike - if you feel like you're being pressured or they aren't listening to you, leave and go somewhere else. And if anything feels slightly weird with a shoe, it can be magnified as you continue running. Mention it to the salesperson and get their opinion.

(How much more can I overanalyze this for you? Haha)
