I had some of the original PF Flyers as a kid.  As they faded away from the market, I moved to Converse Chuck Taylors and have worn those all my life until the new PF Flyers were re-issued.  I still have Converse, and switch between the two, but overall I prefer the PF Flyers.  PF Flyers are slightly heavier, but feel better and more substantial.  In the same size, the PF Flyers are overall a little larger on the outside.  PF Flyers seem to offer more support, but the Converse feels a little more &#34;free&#34;.  The sole on the PF Flyers holds up better in wear and attachment around the sides.  Over time, the inner sole in the PF Flyers can separate and be a little uncomfortable, but this is from heavy use.  I recommend PF Flyers wholeheartedly, and they may add some jump to your step, but buy them somewhere other than Amazon.
