Query: Tongue of shoe slips below laces!!!

I usually like how Asics Nimbus or Kayano's fit my foot--I'm an endurance runner and have used Asics for 7 plus years. I thought I would love this pair, however, I realized when I ran over 7-10 miles, the tongue of the shoe slips down under the laces, which is very uncomfortable!! I was recently in a marathon and I had to keep stopping to readjust the tongue (pull it back out). Finally I gave up, resulting in discomfort and a bruise from the laces, after the race. I was very disappointed and hope this doesn't hinder any other runner or exerciser. Works well for crosstraining--comfortable shoe otherwise.
