I agree with dgosn, chaco quality has declined sharply..
Who knows how low they'll go. First pair started in 2000 and are still around although the rubber has worn through the soles only where the straps run under the frame. No fault of chaco, and the most comfortable thing ever to grace my foot. Ive had three other pairs in the last three years and each ones crappier than the last. I have also seen countless coworkers and friends who live and work outside blow through em. The soles delam in no time, the straps are now made from a more coarse, narrower, grit impregnable, blister inspiring fabric and the footbeds are heavier, harder, less supportive (...i know... how did they pull that off) and the wider checker patern underfoot is not nearly as comfortable as the original fine grid that was smooth as Silk! Also the originals seemed to bend, give and custom form to your foot a loot more than the current models and feel lighter. I'll never pay for another pair...
