A lot of the staff in running shops will try and sell you the most expensive pair, alongside insoles, socks etc.
I’ve worn Nike Pegasus (neutral shoe) for 10+ years, and have never had any problems. I only buy them in the sale, and have never paid more than £75
There’s no evidence to suggest that changing or rotating shoe models gives you any benefit / makes you less injury prone. So once you’ve got a model you like, you can just repurchase the same model whenever you need a new pair. No need to reinvent the wheel and spend a small fortune.
Also, unless you’re running sub-15 5k for men, and sub-18 5k for women, and racing multiple times a month, please don’t believe the Nike Next% / Vaporfly hype. A lot of magazines and blogs have been promoting them as part of their ‘get fit in 2021’ articles, and they have no idea what they’re talking about!
