SPARQ Large Team Parachute
These parachutes offer great resistance training to runners looking to add explosiveness and speed. Just attach the durable chute to the included belt (which is attached to you) and take off.
The superlight, flexible sole helps runners get up on their toes and turn on the speed. These shoes feel supportive, but they're not at all stiff.
My current dog walking shoes. Extremely light and the sole is designed to make you feel like you are walking barefoot.
This is a great, simple piece of training equipment that fits around your waist. Add weights to the belt to strengthen your quads and hip flexors.
