The specific version of the Nike Alphafly shoe that Eliud Kipchoge wore for his sub 2 hour marathon (out of competition) was banned, but subsequent versions of the Alphafly and Vaporfly are legal and still being used to break records today. As a result of Kipchoge's sub-2 marathon run, some rules were set on shoe design, namely:
1. Max stack height of 40 mm
2. Only one carbon plate allowed per show (Kipchoge's had 3)
It's a beautiful city with a temperate climate, nearby mountains and ocean, thriving arts and music scenes, good schools, sports, unique and walkable neighborhoods, and a bunch of other things that people look for when they decide where they want to put down roots. Yes, there is a drug problem, and parts of the city are quite bad, but if you walked around Capitol Hill today you'd probably enjoy yourself and feel quite safe!
