I'm looking for a neutral shoe with a lightweight upper and good cushioning (30mm+ in the heel). I do most of my runs in the Brooks Launch so for something that feels about the same but with more cushioning. I run 90-100mpw almost all on concrete so I'm looking for something to give me extra cushioning on my easy runs. I can't tell the difference between the Brooks defyance or ghost since they weigh about the same and have the same sole thickness. Anyone know the deal with these shoes??
