German sportswear and equipment maker Adidas has reported higher sales and a slight profit rise for the second quarter, despite falling revenues in its golf division.

Net profit in the April through June period was up 1.4% compared to the second quarter last year to €146m, the company said, in line with expectations.

Overall sales, driven by the Adidas and Reebok brands, rose 15% to €3.91 billion.

Adidas, the main European rival of US sportswear giant Nike, welcomed the rise in revenues, as it was compared to a year earlier when the company benefited from its sponsorship of the soccer World Cup in Brazil.

Sales rose in Western Europe, China and the Middle East but fell 14% in Russia, where trade sanctions sparked by the Ukraine crisis and the fall in oil prices have pummelled the economy.

Adidas sales at its TaylorMade-Adidas Golf division were down 26% on a currency-adjusted basis, a result analysts at DZ Bank said was "much worse than expected".

The Bavarian company is working on a new strategy to catch up with Nike, including by boosting digital products.

Yesterday it announced the purchase of a smartphone application for joggers, Runtastic, for €220 million.

Adidas is also working on a concept to make sneakers, and later apparel, directly in the store, from measurements taken from customers, business newspaper Handelsblatt has reported.
