I have only wore these boots a couple of times, so I may be reviewing them too soon. As other reviewers have stated they don't seem to need a break in period, but there is a certain "learning" period. I say this as a person who literally has worn nothing but tennis shoes for years. The learning is getting used to the extra weight and bulk on your feet. I bought these to be a part of my "bug out" plan. I will soon be going on a real hike on rougher terrain to see how they feel then. Plus until I have put many more mile on them to see how they hold up I can't say for sure how many stars they deserve. I give them 4 for now and assuming 200-300 miles from now they are still in good shape I would change it to 5.
Positive

Worked like a charm all over England. I haven't tried the other adaptors, but I found my MacBook to work just like it does here in the US, and there was no difficulty plugging into the outlets.
Positive

I am a big fan of Dean Koontz but not this book. The character Decaulion was boring. I didn't think much of the ending (I don't want to give it away). Usually I'm surprised by the ending, or satisfied. A predictable conclusion.

Negative
