These are amazing shoes, the color IS shocking but everyone says they are REALLY COOL! and I love them (I have 4 pairs different colors)! Light, Comfortable, really durable; they keep your feet cool, too. KEEN is my go to brand for shoes.
All of their shoes are excellent and a really good value. I have several different styles of their shoes, from AUSTIN to CNX to UNEEK, etc!
For sizing follow their chart and you can't go wrong.
