Kate Middleton served up (get it? She was at a tennis thing? No?) a royal spin on athleisuring-while-pregnant this Halloween on a visit to Britain's national centre for the sport.
After taking some time off due to her severe morning sickness, the duchess marked her return to solo royal duties by wearing a new pair of running shoes, specifically some Nike Flyknits that we actually also own and can attest to their bounciness.
While at the centre, the duchess ran some drills..
...high-fived some Andy-Murrays-in-the-makings...
...and appears to show off some impressive "juggling while shaking hands" abilities.
