I have had these boots for two full days and wore them all day yesterday in wet rainy weather, my feet stayed comfortable, warm and dry!

My calves are not small and it took tenacity to get them zipped for the first, second and third time time, since they are leather I know that it only will take some breaking in for them to be snug but not difficult to zip.  This was with a pair of leggings under them - Without leggings they zipped fine.  After wearing them all day yesterday they have already become easier to zip with the leggings on.

So again I would recommend these boots especially if you don't have bigger calves, and for those like me who have bigger calves - know that it will take some stretching and or breaking in - I didn't use a device to stretch mine - I am just letting them break in naturally.

The tread is great and the foot bed comfortable, these boots are a versatile style (in my opinion) and I am glad I purchased them.
