Shoes with laces;Do you put one on first and tie, then the other, or put both on first?

I put them both on before tying

I put them both on, then tie one at a time.

I put one foot in the shoe then I tie it, then I put the other foot in the other shoe then tie it.

Put them on then tie them

I put both on first and then tie them up

I put them both on first then tie them 

I put on  both and then I tie them separately.

Finish with one first, then the other one.
