Hi Christine! No, the foot isn't solid. It is sort of domed, and the curved base of the body of the glass looks as if it is 'sitting in' the foot, almost like an egg in an egg-cup. My second picture sort of shows this.
I always forget the sizes, don't I?
It's 4 & 1/4 " or 11cm tall, 3 & 1/2 " or 9cm diameter at the top and has a 2 & 1/8" or 5.5cm diameter foot. The glass is very fine and rings like a bell when 'pinged'.
Thank you very much for asking
