I think that the general advice has been that diabetics should not use a footspa, but this is only so that the manufacturer is protecting himself, this is in case a diabetic is at risk of burning themselves by using too hot water, for example if you suffer neuropathy and cant sense the temperature.
I know loads of people, diabetics that enjoy using their footspa, just make sure you dry your feet properly and between the toes and use a good moisturiser afterwards (and dont even think of ever walking with fresh moisturised feet on a wooden floor, I have been stupid enough to do that and went flying DOH!)
All the best
