do you have one you would recomend the injini socks dont look all that thick to me from the pics on line anyhow. I'd imagine injinji socks in a bikilia and i might end up with cold feet tho in the trek ascent insulated it might be ok.
too thick and i'm gonna have to size up or something i wore 2 socks once and my toe joints all hurt real bad after a that run and i never did it again felt like cast on my feet with the shoe and all was all very stiff.
I"m a special snow flake too when it comes to cold and feet for running in the past it was a really thick wool sock and i do mean thick in a regular runnig shoe and i'd normally be fine during a run with that sometimes it was a regular sock with that over top but that was if it was like 10 degrees out or something.
for every day wear tho in the winter i'd be surprised if the trek ascent insulated would be warm enough for me. I ususally in the past wore a pretty well insulated boot and if i was going to be outside for hours I have a boot thats ions more insulated just for that purpose its like a heater on my foot lol.
I'd imagine tho for just running around town and such trek ascent insulated would be ok.
I don't have experience with the models you are referencing, but as a winter runner whose favorite is running in snow, I can say that Vibrams can work well as long as you keep moving and/or don't spend much time outside. That is to say if you are going to be standing around in the cold/wet/snow/ice, Vibrams are not the best choice. For running errands and running, I have no problem with Vibrams at all and wear them most of the winter. For running in snow and ice, you should know that your feet will get wet, but the wet-suit effect will eventually warm them up enough, but they will probably never be warm. Think cold but not frozen. At one point I was soaking my feet with my Vibram Flows on before runs, but now I just let the conditions wet my feet and know that I will not freeze my digits off. Every once in a while I may pause to grab my toes and give them a little extra warmth, but I have realized that I will not freeze. I now have insulated Treks/Speeds and find running in them is similar to the Flows that eventually wore out. If you are cold blooded, I would not recommend Vibrams in the winter. When I am not as active outside in the winter, I use the Belville MiniMil boots and cannot say enough great things about them.
