On this freezing day in December, the alleys of Go Sport in Place de la République, in Paris (XI), are almost deserted. Only a large poster “Take the challenge” seems to echo the concerns of the moment. The sports brand, bought a year ago for a symbolic 1 euro by Hermione People & Brands (HPB), the distribution branch of Financière immobilière bordelaise (FIB), is not in its best shape.
