I bought the Lowa Zephyr boots without really knowing what I was buying. I watched some you tube videos and read some reviews. But these boots fit me perfectly. About 4 days after I had received them I went on a hiking trip in the Oregon mountains. My feet stayed dry and even though I did not break these in I had no blisters. I recommend these boots, When these pairs rip apart I will buy another pair. It is well worth the money.
