Been running for about a year now and my longest recent run was 7 miles, which I'm super happy with, but it feels as though I'm constantly suffering from various niggles, all in my left leg / buttock / foot. Obviously these point to a weakness in my left side which I'm working on, but the biggest bug-bear for me at the moment is arch pain. I'm running in properly fitted running shoes so have been gait analysed (neutral). I was thinking of trying the enertor insoles which keep popping up on my Facebook feed, but they're quite pricey so wanted opinions before splashing out! Anyone tried these please?
