I've had my BOA's since they became available. From having the BOA system on hiking shoes for years i've been a big fan and I was in the market for new shoes as my third pair of SST9's snapped on the push off foot (i'm convinced Dexter has a problem with the shoes that can be RH or LH by just changing soles, I continuously have had failures on my push off foot with the base of the shoe cracking and splitting at the flex areas).
Rambling complete, the new SST6s with the BOA seem to be made with a different leather, very similar to the SST9s, they are wider than the SST9s, and extremely comfortable. I've gotten a good bit of games on mine and am a toe dragger and have seen virtually no wear on the shoes and i'm extremely happy with them so far.
