03 BUYING NOTES
Choose sneaker tread for the surface you use
For running shoes, start with the surface you use most. Road shoes are designed for pavement. Trail shoes often have raised rubber lugs that grip loose ground.
Check the intended use in the model specifications and ask for a straight-on photo of the outsole. If your usual route mixes pavement and dirt, look for a model designed for both surfaces.
