yes, very much so. Started with riversheds (2pairs) and then decided to try the Guide boots the last time when they were on sale. The guide boots are great, but I will go back to the riversheds. My estimation is the exterior will last longer on the guides. However, they are heavier and stiffer (good for support, but bad for long hikes). While having the exterior last longer sounds good, my experience with the rivershed is that about the time the exterior shows enough wear, the support within broke down enough where the comfort factor dropped. I buy Simms upper end boots for their sole support and comfort. They are superior IMO. If it was just longevity of the uppers and soles/per dollar, I'd still be buying multiple 90.00 boots. When I was under 35 yo, the support was not as big of an issue. Now it is. The support is both comfortable and allows me to wade more easily.
