You can’t really go wrong with anything from Nike Running’s Lunar output, so it may come down to a preference of style. The LunaRacer series has been a popular one for those who prefer the form-fitting look, with a slimmer Lunar outsole providing that barefoot-like illustration. The primary upgrade from LunaRacer+ 2 to 3 is indeed the Engineered Mesh and exposed Dynamic Flywire, so if you like that teched-out look, these are definitely up your alley. Nike Harajuku has this new Black/White colorway of the Nike LunaRacer+ 3 ready to roll so check out the extra angles below and look out for these at Nike Running retailers soon.
