After six years of averaging 20 miles/week of walking and running (on a treadmill) and washing them once a week, my Bikilas are finally starting to fall apart. Couldn't have asked for more out of a shoe! (Well, maybe a slight heel cushion for my chronic heel spur), but a gel insert took care of that problem.) Went to Vibram's website and it looks like they no longer sell this particular shoe. Can anyone recommend a replacement? Thanks.
