Light and Capable

Size Bought:
6' 3"

They feel light, you can still kick in to medium to soft stuff and put your weight into them, and they protect your feet enough for fast shale descents and a little rocky mayhem… Even if barely. Zippers are a pain but I got used to them. Just spent seven days in them in Alaska, still holding up good. I used them for a quick trip in early may and my feet got cold but that could have been partially the fit/sock problem. Feet staid warm on this most recent august trip though.

Poor Zipper Quality

I've used it once or twice and have initial impressions
Size Bought:
USM 11

Poor quality on the zipper, it got stuck from the first use. It took me almost 10 minutes to unblock the zipper in freezing weather and it no longer works. I had better expectations of a brand like La Sportiva.
