I purchased my All Season
I purchased my All Season SealSkinz on-line from http://www.greatoutdoorsdepot.com
They were on sale for $24.99 when I got them last year. I notice they're offering them for $27.99 now.
I wear a women's size 10, but I was afraid the Medium (listed for women's 8-10) might be too tight so I bought the Large. I should have gone with the Medium.
Just to reiterate, they are probably not the best choice for many of you.
I typically run 3-5 miles, 2-3 times a week -- not a lot of mileage. The high temps in winter where I live are almost always at or above freezing. I'm fine barefoot with air temps in the low 30s so long as it is sunny and dry. As a result, I am able to run barefoot nearly all winter just by watching the forecast and scheduling my runs on sunny days.
I only pull out the SealSkinz during an unusually cold week or when the ground is damp. I mostly used them last year for winter trail runs when I knew there would be freezing cold mud on the trail. They don't have a lot of road wear on them and I suspect the layer of caked mud on them during my runs helped to minimize the wear on the soles. (And, no, they offer no traction in the mud, but it beats having a layer of frozen mud caked on my feet giving me frostbite.)
I expect they'd do fine in much colder temps. They're toasty warm (almost too warm once I get moving), and you could always layer wool socks inside if you found it necessary. I just don't know how they'd hold up to significant road miles (probably not well) or how they'd work in the snow and slush.
BUT, they do provide the best ground-feel plus warmth out of every minimal option I've tried.
Hope that helps.
Peace,
Karen
