éEvery runner leaves their door on any given run, fighting that feeling that maybe this isn't worth it. Adaption to the situation is crucial; control over that little voice is a necessity. So it is nice to know that Brook's new Glycerin 16 provides top-tier comfort with the highly adaptive DNA midsole, a 3D Fit Print upper molds to your foot for a sock-like fit. And if that weren't enough, the rounded heel helps disperse the pressure from each impact. That little nagging voice won't leave but at least your shoes will bolster the other voice saying "but do it anyway!"é
