When I first tried on these boots, I was going to send them back because they were not tall enough for me. I am 5.4 and the shaft is 3" below my knee. I like tall boots to be just below my knee. Then my daughter said they made my feet look huge and I agreed with her. I am a size 8, but for boots I like to buy 8.5. But these boots felt so good, they hugged my skinny calves (14") just right, so my legs were not swimming in the shaft. Most of all, I was impressed with the quality. Of course these are Timberland boots so high quality should be the norm. In skinny or straight leg jeans they look really good and they are super super comfortable. I feel confident that I will be able to trudge through slush, mud and puddles with these boots. I also bought a brown pair, that's how much I love these boots. If Timberland made these boots with a taller shaft, I would definitely buy them. If you want high quality, comfortable, skinny calf, working boots, then get these boots, you will love them. PS: They do make your feet look larger, however I don't care, I would rather have comfortable big looking feet than skinny looking tortured feet!
