Customer Feedback and Results

• Could you use a variety of colors to match shoes?

○ We said that it could be made smaller if we locate smaller magnets, and a variety of fabrics could be utilized to match shoes.

• How heavy is it, and does it add much weight to the foot?

○ Devices are very lightweight.

• Would you add velcro to the side for shoelace security?

○ We would cut the excess lace off, or offer shoelaces of the correct length.

• Does the shoe move around and or does the magnalace come loose?

○ Shoes are very secure with Magnalaces added, and have to be removed with intentional force if the handles are not used.

• Customer said it was a beneficial product that would definitely help those who need it.
