Thanks Grendel...I am running on reasonably new shoes so I don't think that's a worry.
The mid-foot thing is entirely possible though - I have been reading up but I admit I know very little about how my technique and where I strike should change as I speed up.
I do think my style tends towards being 'heavy'. As a cyclist who used to only run in the off-season, I always found I had a big aerobic base and could run good distances as long as I went at a kind of lumbering pace, and I feel that may mean my foot action is not very healthy.
I'm new to posting here, although a lurker for a while. Just thought i'd see if anyone had any tips on reading my wear pattern. If I'm in the wrong forum please let me know!
I have been running for 5 or 6 years occasionally for general fitness, but only this summer started to get more serious and do a half marathon (in three weeks). Training is fine for distance and I'm trying now to add a little speed, but in the process of more intensive running I've started feeling a few aches that make me wonder about my technique and shoes.
When I started out, I went to a running shop, tried a few pairs of shoes and came away with Asics-2110. Felt great, needed no breaking in, etc. I've replaced them with the next year's model most years.
In the intervening period, I had a mid-sole foot injury on my right foot from an assault, which I think slightly changed the way I run. My normal technique made that injury ache somewhat (we are now four years after the event) so I think I naturally came to run defensively to compensate for it.
I mention that because I now have problems with the left foot. Nothing major, just aching around the heel/achilles area a bit. But when I look at the wear pattern on my current running shoes I notice that my left foot now has marked wear on the outside of the forefoot. Nothing on the other sole like that.
So what I'm asking is - do you think this is telling me that I'm in the wrong shoe. (Or perhaps that I'm in the wrong left shoe and my right shoe is fine ?)
