Lightweight racing shoes are the best as they have a low profile ideally suited to POSE running. I have been using Asics DS racers which I find to be the most comfortable.
Yes I did TONS of research....I never do any major change in anything without lots of research. The more I read about it the more it seemed to make sense. Didn't do any classes but stuck to doing the drills that they suggest at the start. Secret is not to do too much at once to allow the calves to adapt. I still alternate my DS racers with my VFF. The VFF are not so good in the dark when you're not used to them, and also if you're in a hurry they can take a while to get on.
Smeggers, that's great that it's not as bad as you first thought You should be on the road to recovery very soon after your op then.
I bought a pair of VFF about a month ago, as for the last couple years I have changed to the POSE style running with the forefoot strike, using minimal style footwear, which I found really suited me and I started running faster too, which is always a bonus. The VFF are great but do take a bit of getting used to at first.
Interestingly enough since I changed to the POSE style, I haven't had any new injuries (touch wood) other than my existing knee condition which interestingly enough hasn't been giving me any pain at all in the last few weeks (touches lots of wood).......don't think my condition is the sort that can correct itself but that would be good!!
I've made a decision to postpone my op as I don't seem to be in constant pain like you are and I really need to get my career in order first. I know health is important too but I know how hard it is to get a job in todays climate and especially to find one that I like doing....that's a bonus. I know I'm prob taking a risk but hey...life in general is a risk!!
