That's what I thought! And they do seem to have generous calf sizing - although not all the shoe / calf sizes are available in the sale. If I hadnt already bought a pair of long boots last week I'd have treated myself.
I've never found boots other than riding boots which fit my skinny calves. Just gone to measure them and at 32cm, I can find loads on this site! Thanks a million. There goes the money for servicing the car.
