I wore these with socks, and they were comfortable. Yes, there are pressure points, but that's what these are made for.
I only wore them at 15-minute intervals every few days when the first spring came off. No big deal, right? Wrong. After about 2 months, they are now completely useless as about half the pressure points have fallen off - and cannot be put back in. Also, the velcro comes off too often for the shoes to be worth saving.
So now I have an uncomfortable pair of sandals that serve no purpose.

I think this was the worst item I have bought in a while. I just wish it had started falling appart faster so I could have had my money back.
Bottom line: chose another pair of shoes, I'm sure one that doesn't have springs and moving parts  and no velcro works just fine.
