If you're prepared to spend some time adapting, then wearing less cushioning is the best way to go. Every part of your training will benefit because of the increase in sensory feedback.
Depending on what you are used to, your foot will take some time to get used to the change in positioning. The key thing to worry about if you're used to chunky heels, especially if you run any distance at all, but even if you don't, is that your achilles will need to adapt to a new length. Women get this problem quite badly when they change straight from office heels to holiday flip flops and wonder why they are in pain so quickly.
So bring yourself down slowly, but if it's safe, go barefoot around the house and every now and then for mini runs on grass to experiment and also to let your toes separate for VFFs.
Every half centimetre of extra cushioning forces your feet to land harder as they search for the ground. The foam acts as a painkiller, disguising any issues there might be, until suddenly your hip or knees flashes up a problem from cumulative errors.
The body constantly works out where your hands and feet will go because it knows how long the muscles are, and whether they are contracted or not, feeds all the data into your CNS supercomputer and creates a virtual model in your brain. If you add anything on to that model it won't work as efficiently as the foot itself. And then when you change shoes....
Running barefoot/minimal sole (with proper technique and exercises) will leave you with no long term injuries but instead replace them with better balance and efficiency of movement, and increase your ability to accelerate and change direction (general agility). Also for longer distances you will be able to run further with less energy. And you will stop pounding your heels and start using the levers in your legs properly.
It will also sort your posture out and enable you to run faster.
Generally though, it just feels a million times better to actually feel the ground, the different textures and surfaces, levels of grip or stability and to be able to harness the elasticity of your muscles and use the GRF to your benefit. VFF will give you this response, as will Feelmax and others. For slightly less connection to the ground, Inov8 f-lites and other double arrows in their range, Addidas RC pros - non tapering, some pumas to mention a few. Just remember that the more 'support' you have in a shoe, the more you have to reply on the grip, partly why kalenji were popular. I personally wouldn't use Flow unless I was in the water because my feet would heat up to much and they tear easily. KSO would be more suited.
And silent/stealth training all the way, like the wise man says.
