I had the Bikilas and loved them to death, and when they started to give up after many many miles I had to look for something else. I had KMD sport at the same time and used them lots but never loved them the way I loved the Bikilas.
I did go out and get a pair of EVOs and was a little skeptical at first but now love them, they are probably my favourite cold weather pair. That being said I think they will be colder than the original. As some background I have gone out for a run in -40C with the bikilas and a pair of ininji so if you are like me norther Texas should be fine. Also it is getting colder up here and I have been out walking with them in the 0 degree Celsius range and as long as my feet stay dry for walking I am fine.
I still use the second pair of bikilas that I had found as running shoes and they are warmer but for everyday use I think I actually prefer the EVOs.
I just bought my first pair of the EL-X and they are snugger then my KSOs(both 44) I use ininji in my KSOs and wouldn't try it with my EL-X.
That being said I find that the EL-X snugness isn't uncomfortable but actually make them feel more like a second skin than anything else. I was highly skeptical of them as I loved my Springs which these were replacing (Wore a hole in the bottom after 2 years of wear) So going in thinking they won't do I was really surprised, easy to get on, and stay on well as my first wear was chasing my daughter all through tunnels etc at a kids play place.
Oh and as for sweat, I haven't found they are any warmer than my sprints were, and they are much much cooler then my komodos and than cooler again than my bikilas. I think that having anything on your feet will catch the sweat if not make them sweat more, but that is unavoidable without going completely barefoot.
I have had the same problem, I did a half marathon last year and then stopped running for a few weeks due to a hectic personal life, and when I went back I had to run predominantly on concrete and pavement instead of trail running. Needless to say it hurt and I pushed and pushed and continued to get worse.
I took some time off again it coincided with a hectic personal life and started back on the new surface in January and have worked back up with limited to no pain at a 17km run today on almost all pavement/concrete.
So taking a break from running for a few days and being cautious and listening to your body may be what you need, however I have read this article on heel pain and it has some interesting studies and may apply in your case too.
I feel your pain, my first pair of blue Sprints and my second pair of black KSOs have started to develop holes on the ball of my right foot in the same spot. Overall they are great and I still wear them but the day is fast approaching after two years of almost constant wear where I will be forced to retire them.
My wife laughs at me as I take off my Sprints and I have one dirty spot on my right foot where the hole is. I don't know about anyone else but I have an almost emotional attachement to my first pair that helped me remember how much I love being in bare feet (or the closest thing I can get into stores with).
But for the price I pay for them she lets me continue as they are the same price as the traditional shoes I used to wear or cheaper and last four times as long.
My favorite of my 6 pairs is my original Sprints, though I find that my KSOs are more versitile for year round and office wear. I have found that both of these models have worn well and have great durability with one of the two pairs on my feet whenever I have to wear something for the last almost two years. That being said if you are looking for something with a thicker sole (Some people don't like mountain hiking with the original sole) I have a Bikila and a Komodo Sport that I use exclusively for running or really cold days. I prefer the Bikila overall except that they are less breathable and warmer in the summer.
I recently moved from Halifax to Ottawa and am looking for some advice on winter use. In Halifax I used some Bikilas with ininji socks all winter long for running and was fine. I was looking at some of the new models and was wondering if there was anyone who has tried them in cold and wet weather.
Last year I used a pair of Bikilas and a pair of ininji all winter long and I was living in Halifax NS. I ran in the snow and probably down to almost -30C all winter long(took breaks if the wind was too strong though)
What I can say is at that temperature when I was running my feet didn't sweat so I would come back with toasty dry feet, but I would do my stretching indoors before and after. At -20 I would take the dog for a 5 to 10 minute walk afterwards but by the end my feet were cold. I found as long as my core stayed warm and my feet stayed dry I was good.
You know your weather and I found the -5 to -10 and slushy were the hardest to find a way to keep the feet warm, if it below 0 and you get your feet really wet they will get cold, so just pay attention to your body as much as possible...
I just bought a pair of Komodos and they are the same size as my sprints, KSOs and one size down from my Bikila. I would echo trying them on is the best way as they all fit a bit differently, and even in batches I have noticed some minor size and shape differences. This is normal for all shoes but it more noticeable for the tight fitting VFF.
PS my KSOs have two toes that are too long for my feet when the other 8 are good. I have found for me this makes running a little difficult as I sometimes trip over the extra space in those two toes(one on each foot). Just be aware of what you are looking for and how differences in fit will affect them. For me the KSOs are great for walking and wearing to work but I don't care for running in them.
