In addition to fixing my flat-footed running sneaker situation, this is how I started being able to run long distances. Over the course of time I built up to a full marathon using this tactic:

1. Brooks Glycerin GTS

Glycerin GTS Mens | Glycerin GTS Womens

My go-to #1 favorite RUNNING sneakers. I genuinely don't like their appearance. I hope the design catches up to the functionality soon because it's hard to buy $160 sneakers I don't wear at all, anywhere except the road.

2. Brooks Adrenaline GTS

Adrenaline GTS Mens | Adrenaline GTS Womens

Brooks Adrenaline are a close #2. For a flat footer like myself, walking, training runs and my day-to-day movement is a joy and a luxury in Adrenaline GTS 22. I have never been able to find the comfort I find in Brooks Adrenaline GTS and Brooks Glycerin GTS.

3. Brooks Ghost

Ghost Mens | Ghost Womens

Brooks Ghost is a solid choice if you don't need a heavily cushioned sneaker. They're a great every day trainer for most people. For my flat feet, these are fantastic for walking and tend to have very cool colors available. But, they fell flat when I tried them to run distance.

Also, consider a new padded breathable running sock. These are my go-to favorites.
