I have not read any of the responses so I apologize if I duplicate a response. I was in the same boat last year. I had hunted in the mountains A LOT for 30 plus years, but had not sheep hunted. Here is the answer to your question regarding gators and two miscellaneous suggestions that I learned on my first sheep hunt that I am taking to heart on the two sheep hunts I have for 2026.
1. I would take gators. I do not know the terrain where you are going, but one does not find Dalls or Mouintain Goats on white sandy beaches. It is almost always wet somewhere. I have Stone Glacier Gators last year, but would not use those. They had a rope that went under the boot and it broke on day 2. I used the Kuiu gator on my Mtn. Goat hunt two months later and loved it. Gators keep the lower leg drier and provide protection from abrasion. I think gators are a must.
2. I took trekking poles on my sheep hunt and started with another set on a goat hunt. I broke a pole on both hunts. In fairness I was in some really bad places stumbled and used a pole to brace myself - broken pole. My guides had long ice axes and I finished the goat hunt with one. I will have an ice axe this year. More stable and provides other benefits as well.
3. I can’t stress enough take boots that are broken in a fit perfectly. Take tape. If you feel a hot spot, stop immediately and tape. In 30 years of elk hunting I had never once had a blister. By day two, I thought I would be find did not tape and had blisters on top of blisters. Good luck.
