Robin Haase is a Dutch professional tennis player known for his blistering serve, which often exceeds 200 km/h. Another interesting fact: he's left-handed but plays right-handed.

Competing in STOX Energy Socks gives him the extra boost to light up the court with speed and agility. Career highs were reaching his ATP singles ranking of world No. 33 in July 2012, and competing at the 2012 and 2016 Olympic Games.
