I ask because by the end of my run last night, the bottoms of my feet were getting a bit sore. It felt as though I had zero cushion left.
My shoes have about 250 miles on them and am wondering if I need to look at getting some new insoles . . . could be the excuse I need to try orthotics!
As I understand it, shoes can wear out anywhere from 300-500 miles, but that range depends also on the surface you run on as well as your weight and running style. I recently completed a half marathon on shoes that have 300+ miles under their soles, and hedged my bets on support and cushioning by adding some green Superfeet insoles about two weeks before the race. Like you, I was concerned about some arch pain I was experiencing towards the end of longer training runs (12 miles plus). I've had no foot pain during training with the insoles before or during the race. I'll probably run on these shoes, with the insoles, for another month or so (120 miles, =/-), and then retire them.
I've never been properly fitted for running shoes, but try to shop according to my running style (mild pronator) and, of course, fit. Last time I bought shoes I drove my son nuts by trying on 13 different pairs of shoes, complete with the obligatory hopping around the store in each pair. I'll probably leave him home next time.
I had a pair of Mizuno Wave Creation 7's which tended to make the ball of my right foot sore from new, though soreness was the extent of it, and it never stopped me running; this was down to the style of the shoe & the fact that I'm a supinator - the 'wave plate' which ran the length of the shoe, was pretty good as a cushioning aid, but a bit firm- hense the soreness. I used them for 700 miles, by which time I was down to the plate on the outside of the left foot, which was a bit stupid really, but it dosen't seem to have done me any harm.
I'm presently wearing New Balance 661's which have proved to be a bit more hard wearing, though having done 450+ miles, I'm seeking my next pair of shoes, so I'm busy seeing what's on offer -
My point is, that dependent on your gait & footfall, you might need inserts, you might need new shoes, though the soreness might just be 'one of those things'
Went out again last night and tried to pinpoint when I felt that foot sore-ness. It was on the downhills that it happened most. I'll see what I can do with my gait on the downhill to aleviate the problem.
On the other hand, I never had this problem before, so I will still look into some superfeet anyway.
At risk of sounding like a fanatic, I started wearing Superfeet in my day shoes about 6 years ago when I was having a lot of knee pain, just from walking around (my profession requires a bit of foot time, visiting job sites and materials suppliers). Most if not all of my knee pain went away with the inclusion of Superfeet.
Since I started running again (about 6 months ago) I had been avoiding using Superfeet in my trainers, as I was testing the theory that running shoe manufacturers knew best what should be happening with insoles in their shoes. I think I've come to the conclusion that while running shoe insoles may be ok in new shoes, they leave a bit to be desired as you get into later miles.
