"these shoes are very stiff. they are not as nice to run in as previous versions"bruehoyt
i had the inspire 3's and the inspire 4's (2 pair each) these are not as comfortable - i think it is because they were made more stiff in the uppers. this has casued pain for me.
i had the inspire 3's and the inspire 4's (2 pair each) these do not show an improvement - the common prob with all models id that they pick up racks, sticks and snow in the large pocket in the sole.
lack of comfort
