These are my very first pair of Clarks. I have wide feet and I've always worn a 6.5 in pretty much everything, but I saw these boots on Endless and fell in love with them so I ordered a 6.5W and 6W. The 6.5W were too big! I labeled these true to size since I've never actually tried a shoe in Wide before. The 6W fit like a glove and they are BEAUTIFUL! The braiding detail on the piece that wraps around the back of the heel is so pretty and the boots are a SOOOOFT buttery suede leather. They just reek of rich!! The shaft circumference is 15".  I have muscular cavles so they're slightly tight when zipping them up, but I can still fit them over skinny jeans.  (Most boots I cannot zip up at all so kudos!)

Excellent craftsmanship. Great purchase! I love them!
