Is it okay to wear shoes a little too big.

I’m buying running shoes online and the only one they have available is for 8.9 inches while mine foot is about 8.7 (8.66)inches. My old under armours were around size 3 or 4 and they are getting really tight and short for me. these new ones are around size 6 and seem like good shoes for the price. So is it okay for that much of a difference or should I just find a different pair?
