Initial review:I had a similar pair of boots many years ago and wore them until the sole and heel were indistinguishable. This Bamboo boot makes an excellent replacement. The upper is the perfect height, hitting one inch below my knee. The actual shoe area isn't lined, so it leaves plenty of room for a thick sock in fall and winter.

One weird thing, the front sole of this boot appears to be coated in microfiber too.

3-Month update: I do a lot of walking and biking. The sole of both boots wore out before the end of the winter. It was an unpleasant surprise. I will not repurchase these boots.
