My barricade 3's lasted forever so when they were completely blown away I decided to buy barricades 4's in the same shoe size. The thing is that it feels like my toes are jammed right against the end of the shoe with the B4's. On the other hand when I put on my B3's it seems like it is more comfortable with a little more space. I haven't broken in or even worn my new B's for more than a few stpes. Should I exchange the shoes for a bigger size or just break them in? Has anybody else had the same issue? BTW my shoe size is 10.5. I have a pair of kswiss walking hsoes that are size 10 and they have plenty of space - just for reference.
