I did a lot of running this winter in VIVOBAREFOOT's road running shoe: the Stealth. They were a great pair of shoes, one of their better features being the spacious toe box which really allowed my toes to splay on long easy runs. But as warmer weather arrived and with it, track season, I started to need some shoes for shorter, faster workouts. The Stealth's toe box was just too sloppy, so I bought a pair of vapor gloves (my second) and instantly remembered why I liked them so much the first time. They fit like a second skin and even at high speeds or on steep descents they never feel sloppy. Somehow they achieve this seemingly without sacrificing any space for the forefoot. Best pair of running shoes I've owned.
