Falke Socks tight rib cuff.

I would have given Falke Socks 5 stars (it is the only socks I wear as I enjoy seamless socks) but I do need to put this warning out there, on two seperate occasions I bought a pair that had extremely tight rib cuffs that caused me serious pain from restricted blood flow. I am petite and have never had this problem the other times. So keep your receipt in case you need to return the socks.
