Setup, Compatibility & Care
To ensure the longevity of your Endorphin Speed 5 trainers, avoid using them in muddy or extreme terrain that could compromise the foam integrity. If the shoes get wet, remove the insoles and stuff the interiors with paper towels to draw out moisture; never place them near a heater, as direct heat can warp the cushioning foam. When fitting, ensure you have roughly a thumb's width of space at the front of the shoe to allow for natural foot swelling during longer, faster runs. Regularly inspect the outsole for excessive wear if you frequently use them on abrasive track surfaces.
