But those muscles are beside the tibia not in front of it and they sure as hell aren't shock loaded when you heel strike. There is more chance of them being shock loaded when you walk and i doubt many people forefoot walk.

When you heel strike their is passive plantarflexion of your foot (the good old foot slaping mentioned above). Even without the foot-slapping it would seem possible that you'll still get this eccentric loading as you try and control this rapid plantarflection as the foot rotates around the heel. This eccentric loading will be passed though Tibias anterior, which normally controls dorsiflexion but can be eccentrically loaded during rapid plantarflexion. The origin of the the muscle is the upper 2/3rds of the tibia..
The muscle is still loaded during walking, but as walking is an habitual activity your body has become accustomed to the stress.
Still interested on hearing your theory as to how forefoot landing increases tibial stress.

they're the muscles that raise your toes, they're the muscles you have to tense during a heel-strike.
hey, there's every chance i'm wrong, care to show me where the toe-raising muscles actually are?
they sure as hell aren't shock loaded when you heel strike.
try this: stand on tip toes - your calf muscle is tensed.
now stand on your heels (raise your toes) - the muscles shown above are tensed.
landing on your heel shock-loads these muscles.
But hey i might be wrong, what's your explanation?
oh god, i'm arguing on the internet, shoot me now.

It increases the forces that "slap" soleus onto the posterior aspect of the tibia.

Can't comment on any forefoot/heelstrike issues, however I suffered from shin splints ages ago at uni, and was taught a very simple stretch which cured it.
Stand with your weight on the outside of your feet, inclining the soles of your shoes about 30 degrees upwards for a minute or so before exercise.
Cheers, Rich

ahwiles - are you seriously suggesting that someone who has shin splints changes to forefoot running? You know - a technique that whilst it can help reduced impact in the hips, knees, and ankles increases the risk of shin splints.
eh? how does that work then? - if you land on your heel, you get a sudden, violent extension of the muscles in the shin. this doesn't happen with 'forefoot' running, so less likely to cause/aggravate shin-splints...
running fore-foot, the only thing the muscles in the front of the shin are doing, is lifting the weight of the foot.
I've had shin splints a couple of times, both times after changing to new running shoes.
The last time I was training for the Safaricom marathon. I'd only been told I was going out to run it about 3 months before the event so a combination of new shoes, overtraining due to lack of time, etc gave me shin splints. After about 10 days I was very impatient so went running, trying not to put weight on the injury by landing on my fore foot, as you describe.
Result? A lovely groin strain which meant I had a whole month of no training before the event, a marathon completed with industrial amounts of painkillers, and 3 months afterwards trying to get rid of the groin strain.
Without having any scientific evidence, I'd say if you get shin splints take a couple of weeks off, get rid of them and train carefully after that, otherwise you risk giving yourself other problems.
