Hello. You are entitled to an annual foot inspection by the diabetes nurse at your surgery, but the test I get is limited to a sensor probe on my toes. You may find it's up to you to ask to be referred for more detailed examination.
There are several threads on here about different sensations people feel in their feet, from heat or cold to pain or a feeling of walking on cobbles.
There are also several threads on appropriate shoes etc, based entirely on our own experiences. And of course at our own expense!
I had a (private) reflexology treatment recently which increased my knowledge of my feet but we agreed this kind of treatment isn't likely to affect conditions of the feet caused by diabetes.
