Comfort is paramount to me.  I spend most of my time in slippers, even though I'm pretty active.  I work at home, and at 55, I've been through numerous surgeries and have implants in my lower back, hip and both knees.  I've tried dozens of slippers.  The Sorel Nakiska slippers keep my feet warm without feeling hot.  When I first put them on, I was a little worried because they felt a little unbalanced.  But within an hour, the slippers had molded to my feet and provided the oft-missing support of other slippers.

I had been a fan of Uggs before they became famous, and had several pairs of slip-on slippers.  The Uggs were ok after I broke the sole by bending the slippers in half with my hands.  But there was no support whatsoever, and they sometimes slipped off of my feet while walking.  Most recently I had been wearing Keen Felt slippers, and wore out two pairs.  That wasn't difficult, because the felt was constantly pilling and then shedding big fuzz bunnies.  I was loathe to give them up even though they looked terribly shabby.  Birkenstocks, for whatever reason, caused foot pain for me.

The Sorels are not the kind of slippers that you can put on without the help of your fingers, but they are worth that extra step.  Pricey?  Yes, but worth it.  You could go outdoors with them, but there is not much of a tread, so things could get "slippery" if there is snow about.

I wear a 7.5 to 8 US, and found size 8 to be perfect, either barefoot or with a pair of not-too-heavy socks.  I have a medium width foot and relatively short toes.  Remember that anything with shearling and leather is bound to stretch after a while.

I think the Sorels look terrific too!
