Until a few years ago, I never knew indoor soccer was a thing. I went with some friends to an arena in Manchester to see her daughter in a game. Too my surprise, the field was inside. The game is played a bit differently inside. Each field is surrounded by a 4 foot wall, which players can use to their advantage by ricocheting the ball off the wall, either to another team member, or towards the goal. Sort of like a pool ball on a pool table. As someone who grew up playing soccer at school, it was something different to get used to.
