It just seems that new shoes always feel good, since the elasticity in the sole is still new.  However with an all around running shoe, like this trail runner, one has to take it off-road for a bit as well.  The shoe is not the lightest but keep in mind your stride.  I find the weight of a shoe helps maintain momentum when running at a constant pace and these shoes seem well suited for my build, 5 foot, 11 inches with a 32 inch inseam.

Traction off-road was excellent up muddy hills.  This time of year we have wet leaves on the ground which requires some caution with any runner wearing any shoe.  In general, I have found a tire tread pattern seems best for off-road trainers.

The fit is true to size.  I did not have any heel slippage.  However, like most running shoes today, there is a pair of small ankle lace holes which one can use.

As a rule, I typically replace the flimsy factory inner sole with an orthotic style inner sole to support my flat arches.  Unlike some running shoes, these did not come with various sized arch support inserts.

Other than some mud puddles, I have not had a chance to test the gortex.
