I switched from Simms vibram to Simms G3 Guide in felt. Best decision I ever made. Vibram was great out of the water, but even with studs it felt like I was walking on bowling balls in the water. I will trade out-of-water stability for in-water stability every time.Switched back to felt few years ago from the Vibram and felt wins hands down.
Man, those boots look interesting. We are looking at another trip to Alaska next year, and there, felt is illegal. Last trip I brought my Korkers and I ate **** daily. Not only that, but my buddy had a sole come apart. Not a good place for that to happen. These Patagonia aluminum boots look great. No need for interchangeable soles, no felt issues(mussels) and no slip issues with rubber. Thanks for sharing.Neither felt nor vibram are very good for Colorado. Our rocks are too slippery for vibram and the hiking and snow make felt a poor choice as well. Aluminum bars are all the rage now.
I have not tried them yet, but I've heard great things.
