I bought a pair of Vasque Wasatch boots on April 2011 and by December 2012 the sole on the left boot cracked open all the way across from side to side. I had read the other reviews about this happening but went ahead and purchased a pair anyway.  I probably put a few hundred miles on the boots until they split open.  Do not buy these boots unless you want a pair of disposable shoes.  I must say these were the most comfortable boots I've ever had...never a blister or hot spot.  They performed so well on serious hikes.  I well miss them.  It's a shame that Vasque can't get it's act together.
