For those who suggested using needle to pop the blister, if you
do that it will infact prolong the healing process or make it worse
(risk having an infection) so don't.
Just cover it up to avoid further rubbing on the blister. It should
go down in 2 days by itself.
TS, are you wearing new shoes? Are you wearing socks inside? If it
continues, it might be worth getting another pair of shoes.
