This is how in brings better typography:

Oldstyle Figures (onum) displays numbers in varying heights and alignments. These numbers blend in with lowercase letters, as they share the same x-height, and also have ascenders (usually 6 and 8) and descenders (3, 4, 5, 7 and 9).

Oldstyle figures are often considered more pleasing and less intrusive than lining figures. They are preferred in running text and also pair nicely with small caps.

Fonts that have this feature includes EB Garamond, Lato, Source Sans Pro, Roboto and Open Sans. Try them with text like 10Broad36 and 123456789.
