For whatever reason, the seconds AE made for Brooks Brothers and Ralph Lauren frequently get marked down to the ridiculous level of $129. As noted above, the only difference is the sole and the poron insole. As for the difference in fit, there was a good description a page or two back. The report was that the width and length are the same, but there is less volume in the shoe due to the space the poron insole takes up.
Have not checked yet, but have checked the Brooks Brothers site to see if BB will sell the Strands in suede. I can't justify paying $200 for seconds when firsts are not much more than that, but I would buy seconds for $129.
Just because it is corrected grain does not mean it is not also full grain.
