If you're light on your feet when you run, you probably like a light shoe that is responsive rather than one with pace-robbing cushioning. Salming's Speed 3 Shoe is built for runners who have a quick stride that doesn't rely on heavy heel strikes.
The Rule of Five represents the principles behind Salming footwear. Light, flexible, flat, thin, comfortable. It's the basis of all their platforms. The 5mm drop puts your foot in a natural position, allowing you to take advantage of your foot's spring and flexibility. It's supported by their SpeedLite compound across the foot and anchored by their RunLite midsole. It gives you a better feel for the ground. The outer sole is comprised of lightweight blown rubber to minimize what you have to carry around while still sticking like Velcro to the ground.
As for the rest of the construction, the Speed 3 ticks off Salming's most famous features. There's the TGS 62/75, which is their way of controlling the shoe fore-aft flex to mimic the foot's natural flexion. There's a flex point 62% of the distance from the heel to the toe. And rather than flexing straight across, the flex point is at a 75-degree angle, which mimics how the ball of your foot is angled across from the outside to the inside. And, as with all Salming shoes, the upper is light and thin and bonded to an exoskeleton that wraps around the foot, keeping it firmly in place and eliminating lateral slop.
The Salming Speed 3 Shoe adds emphasis to brisk runs.
