In The Flash s3e3, named Magenta, Jesse Quick, now a speedster, ran in an eight-like fashion to create enough upthrust to make the tanker float in the air till Barry convinced Frankie to come back in her senses.
What stings me is that Jesse ran speedster-ly without wearing the special suit other speedsters wear.
How could she do so?
The suit is designed to "withstand the high speed of movement" i.e., to protect the speedster from severe heating and other wears and tears experienced at such speed.
How could she run without wearing the special suit?
We have seen quite a few times though that Barry, too, also can run in his civilian dress without getting adversely affected.
So, the query should be re-aired as:
What is the point/necessity of the special suit if speedsters can do their job without it?
Or is it that speedsters can run comfortably at somewhat not-so-high speed without wearing the suit and that they need it only while going at near the speed of light or above?
