Change in running shoes

I wear custom orthotics, so I have to wear a neutral running shoe.  For many years, I have worn Asics Fortitude.  Most of the time, I have been able to find them at a reasonable price online and buy several pair.  However, in the past few months, I cannot find my size 13 anywhere.  Recently, I bought a pair of Saucony Eschelon at the Fleet Feet store.  I have been walking in them for a couple week and ran in them for the first time today (2 miles on the park roads).  Maybe I will get used to them, but I did not feel much cushioning.  I probably did not run any faster than normal, either.
