Awhile back I asked if anyone else had very large calves, and if they had suggestions for knee-high boots. I received many helpful responses.

I've been on the hunt for the past month, and I'm thrilled to have found two pairs of boots that fit my 17.5 inch calves. The first pair is the Clarks Derby Palace in mushroom (they also come in black leather), which I bought at the Clarks Outlet for $99. Zappos lists them as a 16 inch circumference, but they fit my larger claves comfortably - although I cannot zip them over skinny jeans unless they stretch a bit.

The second pair I found at a great local shoe store. They were quite pricey, but I was willing to pay nearly anything for well-fitting black leather boots. They are Pikolinos brand, and I cannot find the exact match online, but they are quite similar to these boots (which I notice are a great price!).
