Shoes are highly individual, so take what I say with a grain of salt. You may find you tend to slip going downhill with the relatively smooth tread on the sole. Lean forward a little going downhill so your center of gravity is over your foot and that will help. It will also help if you have trekking poles.

As someone else said, your pack weight is heavy, especially if you haven't added the weight of water. Lightweight backpacking is more about what you leave behind than what you take. See if there are some unnecessary things you can eliminate. Even a few pounds can make a big difference.

Enjoy your trip.
