When football clubs replace worn equipment, most fans assume it ends up in storage or is thrown away.
Arsenal's old player socks have taken a very different path.
The Premier League club recently donated around 40 pairs of footless red socks to Redwings Horse Sanctuary, Britain's largest equine rescue charity.
What sounds like an unusual gift has become a practical tool for caring for rescued horses and donkeys.
The long sock sleeves are now being used to protect sore legs, keep flies away and secure bandages during treatment.
