I scoured the web for lightweight, waterproof hiking boots that people  rated as comfortable and not requiring much break in. I settled on these Oboz boots based on reviews on REI and other afficionado sites. I guesstimated that 1/2 size larger than my regular shoe size would be appropriate based on the comments. I was not disappointed. The size was right with moderately thick socks and the boots were very comfortable and easy to wear for extended periods of time. I took them on a trip to Lake Louise where I hiked about 10 miles, not to mention wearing the boots every day for a week. I didn't have a hint of a blister or any other signs of poorly broken in boots. Highly recommended.
