[quote="sergio"]I'm thinking about giving this type of shoes a try, but at the same time I'm kinda terrified.
Pros: Starting from scratch.
Cons: Long history of pain and troubles with running (left foot/ankle, right knee).

There is also an accompanying iPhone app if you have one.
I basically started by wearing zero drop shoes just to walk around in (Newfeel Many from Decathlon, a nice cheap shoe for seeing if you actually like running in minimal footwear before splashing out on something nicer) for months and months before starting to run in them. I also only ran trails as it strengthens your feet and calves, forces you to vary your footfall, and promotes treading lightly (because hitting rocks hard in minimal shoes hurts). At the end of my runs I'd take off my shoes and run the last few hundred metres barefoot, and gradually increased the distance. Eventually I bought some Trail Gloves, but I still use the Newfeel for roads as I haven't been running roads much. My new schedule has a bit more road running in, so I'm probably going to buy another pair of shoes for those sessions. Most likely Skechers GoBionics.
For really muddy conditions or snow I wear Salomon XA Harriers, which are basically Salomon's pre-Speedcross fell shoe, but with the same drop as the Speedcross 3 (the original had a 12mm drop, the 3 has 9mm). Now that I've learned to run properly I can still avoid heel striking despite the 9mm drop (if only they'd carry the 4mm drop of the Fellcross over to the Speedcross, or just make the Fellcross more widely available).
