Foam football
The closest thing to a genuine all-rounder for indoor play: light enough not to do damage, but with enough shape and bounce to still feel like proper football. Good for most ages and rooms. If you only buy one thing, this is it.
We went through three balls before finding one that didn't end in a breakage or a bored child. "Soft ball" isn't one thing, it's four different things, and they're not interchangeable.
If you've grabbed whatever ball was nearest before, it usually goes one of two ways: something gets knocked over within five minutes, or the ball's too light and floppy to move properly and the game falls flat. The right ball depends on your space and your child.


Soft isn't one thing
The best ball for indoor football kids will actually enjoy isn't one product. It's a choice between four different options below.

Sounds like a joke, isn't one. Zero cost, zero bounce, completely silent, and fine for rolling and gentle passing games. It doesn't work for a proper kick or hitting a target with any force, it just won't travel far or predictably enough.
Best for the youngest kids or the gentlest games: slow, forgiving, impossible to really hurt anyone with. It's unpredictable in the air though, so it suits keepy-uppy better than aiming at a target.
Designed with a low bounce so it behaves indoors; worth having as the main ball once your child's older or more into the sport. It costs more and has more presence than a foam ball, so it suits a bigger room or a confident player better than a nervous beginner.
Weight first, size second
Weight first, size second. A ball too heavy for its size is the thing most likely to cause a breakage or a bruised toe, whatever it's labelled as. If unsure, go softer and lighter than you think you need, you can graduate up once you know your space and your child's style. Going the other way, after something's already been knocked over, is a less fun way to learn the lesson.
The research behind it
There's a reason going softer and slower than you think you need is the safer default when you're working out what ball to use for football indoors, not overcaution. A study comparing how quickly children of different ages react to a moving ball (Olivier, Ripoll and Audiffren, 1997) found reaction time to an incoming ball improves steadily with age, and younger children are markedly less able to prepare a movement in advance than older children or adults. Read the study on children's ball-interception timing. This is a small lab-based ball-tracking study, not one of football play or injury rates, and it misses the youngest end of this site's 5 to 9 age band, so it supports the general pattern, not a specific injury claim.
