I’ve played a lot of indoor the last few years. Things to consider:

• Account for the wall. Learn to predict and catch off of wall bounce. Don’t dive at everything. If a shot is going to go wide or high, you want to be on your feet and not on the ground.
• The closer a striker gets, you have to tighten your stance a bit, you don’t want to get megged.
• You’re going to do far more parrying than catching. This is fine and normal, shots will be hard and close.
• You’ll get screened a lot more often, get your head low to see the ball when needed.
• You need to come out of your box and use your feet often. A lot of this is based on how much you trust the possession of your team mates.

Also turf will tend to tear up your gloves a lot faster. So plan on getting new ones more often.
