Adidas is no stranger to technology by any means, but it clearly feels that it needs a leg up -- the fitness equipment maker has bought fitness tech firm Runtastic for just shy of $240 million. Both companies are wonderfully vague about what the deal entails, beyond extolling the virtues of a "perfect match" and helping Adidas "unleash its knowledge of sport." However, you'll be glad to hear that this isn't likely to deprive you of those all-important apps or wearables. Runtastic will live as a separate entity within Adidas, and it doesn't expect much to change on a day-to-day basis. For the most part, this means more cash and technical possibilities.
