It's hit or miss, just save the receipt. Personally I've gone through 3 out of 4 pairs of the OG XX8 (6'1" 196 lbs). Worst case scenario, you take them back to the retailer you bought them from for a credit, or you can send them back to
http://nikeclaims.com if they pop within 2 years, but you lose out on taxes and shipping them back to Nike this way.
I picked up my first pair of SEs yesterday and started breaking them in today at the gym before SB. The cushion definitely feels firmer than the original, but in a good way. They were also a little stiffer than the OGs out of the box, which obviously got better after playing a couple games of pick-up.
