The breathable mesh upper is made from lightweight material to provide premium comfort and ventilation. The ADAPTER-FIT technology promotes flexibility, adapting to the shape of the foot, even when there is swelling over long distances. The overall shape of the TrailFly Ultra G 300 Max is a bit on the wider side to offer you extra space.

HOW TO CHOOSE THE RIGHT SIZE FOR RUNNING SHOES
Your running shoe size will generally be 1 to 1.5 sizes bigger than your regular (‘dress’) shoe size. Bear in mind also that one foot can be slightly bigger than the other.

LENGTH
First, kick your foot back into the heel of each shoe before checking how much space is left at the front. When standing in each shoe with your full weight on the foot, it’s best to have between half and a full thumb's width between the end of the longest toe and the end of the shoe.

WIDTH
When standing in the shoe, it’s best to have a little wiggle room for the toes, but the back of heel should still feel nicely secure.

SPIKES
Sprint spikes are best when a close fit. Distance spikes best when up to a half a thumb's width between the end of the longest toe and the end of the shoe.
