That's awesome you were able to run your best yet!!
My first pair of shoes that had the tongue attached to the sides were a pair of nike air shox. I thought it was weird and dumb at the time.... little did i know that shoes built like that seem to be my favorite now. Thank you for the update! Hope they do you well in longer runs, like they did here!
Yes it was a nice surprise to run that fast for the first time with them! And I agree with you. Before testing a shoe with the tong attached, I didn't know the usefulness of it.
I will do my longer run with them tomorrow and I will try do a post about it tomorrow as well :)
