Well I was dead set on the Lowa sheep hunters butttt... I looked at them multiple times and I was not that impressed with the fit and finish for a $300+ pair of boots. I am not saying that they werent solid built but of the three or 4 pairs I checked out the rubber protective wrap that is just above the sole had visible glue at the seam which does not mate very well at the back of the heel. Enter the kenetrek, they are just very cleanly put together and "finished". I havn't put any mileage on either the lowa's or Kenetrek mountains but they are comperable in feel. They both have great ankle support and are extremely comfortable. I liked the uninsulated lowas but I don't think that 400 grams in the Kene's will be uncomfortable especially because I prefer to wear thinner socks and my hunt is in September. Well I went with the Kene's and I am planning on heading up the mountain with them on Friday so we will see if the $265 spent was worth it!
I also bought a set of Vasque GTX mid height boots for the wife they are the most comfortable we have found for her so far since she broke her ankle in 2005. The seem to have very good ankle support without weird preasure points.
