Wow, way to go! I'm glad to see they were still holding together (kind of) after that many miles! I'm only at like 200km on mine and was concerned about the amount of wear, but after seeing yours I see I have many more miles to go!
Check out podrunner.com, you can pick whatever bpm you want and it's about an hour of just music. I find I don't really listen to it, but it keeps my feet moving. I have 2 that are 180bpm that I alternate between.
It partly depends on if it's just overuse pain or injury pain. I know when I started increasing mileage in my VFF's my calves would be sore for a day or two after, and as it subsided I could go again and push a little further. Then a little over 6 weeks ago I experienced the other end of things--part way through a run I had a stabbing pain in my right calf and it wouldn't work its way out like I thought it would. I rested a couple days, tried again and it grabbed after a mile and I couldn't run another step, tried again a few days later, same thing, I ended up going for ART and it was about 4 weeks till I could run more than 5km with no pain again. Fortunately it healed in time for my first half(I went into the half not having run more than 7km at a time in 5 weeks), but I had to sit one race out in the meantime because I could only do 3k by then (2 weeks after the initial injury).
From what the chiropractor who did my ART told me, if you're using a muscle a lot without having adequate recovery time, you form scar tissue in the muscles which decreases the stretchiness of the muscle, and the you can get tears or pulls or whatever a lot easier. He treated it with ART (active release technique) and Graston technique to break down the scar tissue, icing it 3 times a day, a lot of stretching, and high dose omega 3 oil (supposed to be a natural anti-inflammatory and help with muscle recovery). So, if you have some soreness and push it too much, this is what you could be looking forward to. Now I'm on the bandwagon of giving more rest than you think. As well, my chiro recommended strengthening the muscle without aggravating it, by doing things like squats, lunges, toe raises, standing on one foot using toes instead of ankle to balance, one foot toe raises, etc. I hope this helps you to be proactive and avoid the problems I had!
I've been waiting for these, too, but in the mean time I just found a pair of Mizuno Wave Musha 2's for $49! I haven't taken them for a run yet, but so far I'm impressed with how light they are, very flat, and the top is so light and stretchy it feels like it's not even there! I"m hoping these will be good for wearing with thicker socks for some winter running.
I have roughly 200km of running on each of my KSO's and Bikilas, have owned the KSO's since April and the Bikilas since July, and have worn quite a bit of the thickness of the big and second toes away. I guess there's something wrong with my form, but I don't know what it is and have done a LOT of reading and experimenting to try and figure it out. I'm thinking that if I get some time to run on a track this winter I"ll try to go barefoot and see what happens. That being said, for those of us without perfect form they don't wear as well as I had hoped. I expect within another 100km I'll have pretty much worn right through the toes of my KSO's, and hopefully I'll get another 200km on the bikilas before I'm more truly barefoot!
With KSO's you should be fine to thread it on the velcro strap. I wore bikilas for a run with a DTag timing chip last week and it was fine, and I've seen the ChampionChip ones go on the velcro strap as well. My brother-in-law wears shoes with no strap or laces or anything, and he just used safety pins to attach it to his shoe!
I'm a fellow Canadian, welcome. I used to hate running, but after having 2 kids and learning a more efficient way to run (which I learned because of my VFF's), running is now my way to stay sane. I was injured for a few weeks and really missed it. I couldn't believe it, I was always the kid who started dreading the next Track and Field day (the next year) the second my events were done. On Saturday I ran my first half marathon, and I plan to do another in May. I hope you'll give it a chance!
I did it!!! Ran my first half marathon, and in bikilas! My time was 2:19, which I'm happy enough with. Originally I wanted to do under 2:15, but after taking 4 weeks off pretty much I was hoping for 2:30, or really just to be able to finish. The last 5k was pretty hard, especially because of a wicked headwind, but I did it. My calf actually feels fine, it's my hips that feel like I ran too far! Now I'm planning to take some time off and then build back up slowly over the winter to do another half at the end of May, and see what I can do when I'm actually prepared!
