I was a diehard Dyad user for years. I can attest they are great for those of us who need support, whether you have flat arches, or just need more cushioning. But these jogging shoes, at least on me, do not last long.  When they first came out, they were $85 and one could usually find a sale for maybe as low as $65. But Brooks just kept upping the price that, the last time I looked, full retail was almost $130. Wow. This is not a $130 shoe.
 Okay, so I am pounding the pavement between five and six times a week for an hour, at a fairly decent stride (no walk-run stuff). So I expect shoes to wear out. But these are out of shape in less than three months. Any shoe that cost $130 had better last longer.  Just my humble opinion. The recent colors are awful, to boot!
 Brooks needs to be more realistic in the pricing, then they get five stars.
 Otherwise, the Dyads do provide good cushioning. Any decent jogging shoe ought to provide arch support but these do a bit more.
  Price considerations sent me back to the Brooks Adrenalins. I just double up on thick short socks.
