I bought a pair of 34s from a Nike outlet store (okay, maybe that’s my first mistake), and they’re falling apart after 80 miles!! What?? I thought these were supposed to be a reliable trainer. By falling apart, I mean the black rubber undersole is ripping from the white midsole. Some strong glue will likely do the job, but still. Disappointed in Nike. Guess I’ll stick with my tried-and-true Adidas Solar Glides.
