When to get new running shoes

[Allfurcoatandnoknickers]

I am 55 and have been running for around 3 years - not much - two runs amounting to around 5-8k a week.
I wonder if there is a rule of thumb people use for replacing their trainers? I got my latest pair (Brooks Ghost) last August.
I noticed that I've been getting some heel pain in the mornings (burning sensation) that I've had on and off over the years.
I wear special orthotic podiatrist made inserts for running and hiking.

I look at the soles, I'm a heavy over pronator, I go through a pair every 9 months or so.

Thanks - what do I need to look for in the soles particularly? I'm just feeling that there isn't much 'bounce' in the soles any more - apart from that they have been so comfortable!

There's no set rule in terms of mileage - it's much better to go by how your shoes feel and whether you are starting to get any niggles. If you feel there is no bounce in them then yes, it's probably time to get new ones. That's always a sign your shoes are past their best.

Great thanks- I’ve booked in at the running shop!

My husband replaces his running trainers every 500km which for him is around every 8-10 weeks on average so he does get through a lot of trainers, more in the summer as he might run 10k or more every day in summer, less in winter. He never wears the soles out, but there is a noticeable difference between the springing of the soles at the start and finish and he says he changes them for the shock absorption.

I don't know if this is going to be relevant but if you have Vitality health insurance through work then you get 50% off any pair of running shoes at Runners Need once per year as one of the benefits.

So if you have a work insurance policy or 'perks' programme it's worth checking.

I notice that my legs get niggly and achy in different places when my shoes get tired. At the same time the treads on the soles are showing slight wear and often the fabric is going at the heels or inside of the top. It's typically about 400 miles or about 2 pairs per year as I normally run 2-3 HMs per year. This year they've lasted longer and done 9m as I've run less.

I phase the old pair out and use them for casual wear until they're really trashed.

Strava tells me roughly when time to look. It did recently, I got the next pair in and tried them out for a couple of runs. Legs felt much bouncier, so I have retired the old pair to walking shoes - I find I can wear them a fair bit more that way.
