What the hell, right? Went to REI and the wife was really into the idea so I tried on a pair as well. I have high-ish arches, so I was a little worried about how that would work out with a relatively flat looking shoe. The models on hand were limited, so I tried one on that had the strap across the top. This managed to pull the insole right up to my arch, so that was kind of nice.
The sales girl was actually wearing a pair herself and seemed knowledgeable on sizing, etc. I began asking about the KSO Treks and, as if reading my mind, she asked, "Are you planning on hiking in them?"
"Well," I said, "I've considered it."
She simply gave me the "maternal" look and said, "No. No, don't do that," while shaking her head. Seems she wore hers up in Arkansas and while great for water crossings and camp wear, she found them to be not so fun on the rocky soil there. Granted, she wasn't wearing the Treks, but those are only a slightly beefier sole with the big upgrade being the leather upper.
The wife, on the other hand, absolutely loved them. However, when it came down to it, they were really expensive water crossing/camp shoes. So rather than drop money on those, we used our member coupon on a nice set of Merrel hiking shoes that were very similar to mine. Her current boots are crap.
The wife will probably buy a pair in the future, but I'll probably take a scale to wal-mart and pick out some cheap water shoes or sandals with enough straps to anchor them to my feet in rivers. To be honest, if I had 100 bucks, I'd get the Treks, but I'm a student and my wife is a teacher, so cheap target/wal mart water shoes must take budget priority.
