I found that perfect sized replacements Keen Austin insoles can be found on Amazon are in fact manufactured by Keen themselves. Here they are: Keen Austin Replacement Insole
I happen to wear size 13; so went with the "X-Large" size. In my case, the insoles were a perfect match size-wise as the original insoles found in my Keen Austin shoes and required no cutting or trimming of the replacement foot pad. While these insoles don't look the same as the original Keen Austin Insoles, they are shaped exactly the same (the replacements are bright yellow and black). The new keen austin replacement footbed insoles are a bit firmer than the original (the softer feeling Keen Austin replacement food pads can be found here - but I can't vouch for them). While they are a bit firmer, I suspect they might last longer than the original keen insoles for the austin shoe.Find your replacement Keen Austin Insoles here:

They measure in at just about 34" flat to flat, but when the weight of the Jeep is on them, I'd say they come in just a hair under that measurement. They really are a nice looking tire; as they look almost as aggressive as a mud terrain. That being said, their road manner is amazing; extremely quiet and comfortable. I've not yet had the Ridge Grapplers off road, so can't report on that yet. They do just fine in the rain on my Jeep JK. The Nitto Ridge Grapplers have two sides to the sidewall. One has more "lugs" than the other if you want a slightly toned-back look.
