These are well-padded boots, and were very comfortable on my feet, even after half a dozen miles and 12-hour days. The air mesh upper is designed to vent heat, so they're not ideal for torrential rains, but when I soaked mine while recovering a peccary from the Rio, they dried out fast and didn't cause blisters. The GTX models come with Gore-Tex, but that seems unnecessary if you're looking for a desert hiker. At $150, they're not cheap, but my last pair of Vasque's survived for almost 10 years—that's a downright steal. BUY IT NOW.
