Skin on my feet very tight feeling. why? no pain, no tingling, no numbness, feet are warm?

It is possible you have some fluid accumulation in your feet. This can be from sitting with your feet down for a good part of your day. Something as simple as elevating your feet on a footstool during the day can be very helpful to prevent this swelling. If that is not the case, your doctor should take a look to see what else is causing this sensation. Good luck!!
