I guess it completely depends on what you want to achieve. If you want to be a forefoot runner then IMO yes, minimal shoes will help as you'll find you natually migrate to your forefoot.
I migrated to minimals in January due to ongoing injuries and discomfort whilst wearing more conventional shoes. I've not had any problems since. In fact I've made more progress in the last 3 months of wearing them than I did the 6 months previous (I'm new to running). Pain and discomfort was limiting me to
Popping by after a little break from the reading the forum; I've used the time away well spending most of it out running! Far more productive use of my time.
I say running...still at a steady jog really.
I've not posted that much detail on here in the past so in summary:
BMI 30, 4 - 5 stone over weight,
Couldn't run for more than a minute
Started off with C25K last August time
Suffered with numb feet and painful legs/back
Made a move to minimal shoes
Progress has been good since early January and moving to minimals, at that time I couldn't run more than a mile. I'd never have dreamed that 3 months down the road my short runs are 2.5 miles, my 'normal' runs are 3.5 miles and my longest run is 5.26 miles.
For me keeping going through the not so great weather has been key. If I could manage through that then I could manage through anything!
I'm at the stage now where I don't really (ok usually) have to force myself out of the house and dare I say I really do enjoy it. I'm now getting a kick out of the discomfort that comes with distance and the desire to keep on pushing and going futher.
I'm not going to win any races with a pace of around 13 mi/mile but I'm sure a pace will come with time.
I have a lumbar problem (waiting for a fusion) and have suffered with aching feet, numbness in my feet and left leg, sciatic pain and....well general discomfort. Picked up some minimal shoes and haven't looked back.
Not a niggle in the 3 weeks I've been wearing them.
Interestingly I've noticed I'm running far more efficiently (further, a little faster with lower heart rate)
