Tiffany Beers is a former Nike employee responsible for creating the self-lacing technology seen on the HyperAdapt 1.0. She recently left the Swoosh to take a job at Tesla, but she occasionally creates sneaker-related videos for her YouTube channel, including the one seen above.

In the video, Beers compares the Nike Epic React and the adidas UltraBOOST sneakers – tow of the best, or at least most hyped, running shoes on the market. It’s interesting to hear a former shoe designers take on the models. Ultimately, she decides that the Epic React is the better sneaker, which may be a somewhat biased opinion. Watch above.
