I'm new to this, I've run quite a bit in the past, but never in any dedicated fashion! Looking for some new trainers to get now the weathers getting nicer so I'll be out more. Is it worth investing in an expensive pair? Or even going to a shop and having my 'gait' monitored or whatever it is they do! Do people find cheapish ones ok? I really want a good pair, but don't want to spend so much.
If you go and have your gait analysed you can pay for some insoles, and then use these in a cheaper pair of trainers. I went to the Sweatshop in Teddington for this. Insoles cost me £45. Then I bought a pair of Brooks Ghosts which cost £100
Depends how far and how often you are running. You might be able to get away with a cheap pair if you're just doing 5k a few times a week. I had some cheapo Nikes that were fine until I started running more than 5 miles, then my ankles started killing me so I got a gait analysis and got some Brooks Adrenaline.
There isn't a 'best' brand, different shoes suit different feet.
