Footlocker has the the Superfeet and Spenco brand which I have used for years now. The Spenco's are flatter and mold to your foot's shape after use. They're not $40 bucks either but those superfeet insoles look awesome.
Do the Spencos raise the heel and reduce footprint length like the Superfeets do?
I much prefer the price if they'll allow me to comfortably fit into the size 13 Prions. The 14 FTs that are on the way cost $20 more than the laced version anyway, so I might try those.
