@Matt - Novesta is pretty firm as well in that sense, i have a pair of their low sneakers, starmasters, and though i beat them up daily, and almost destroyed the soles on bike pedals, the midsole does not unglue
Not usually my thing but I picked these up from North Sea Clothing for the summer and I’m pretty pleased so far. Dress down day at work ahead of our summer party and I’ve had a few positive comments.
