The Soles of the Season campaign also encourages workplaces to support the charity by setting up a Christmas tree with trainer laces and tree tags for messages to be tied to the tree.
It is also asking people to decorate their trainers with seasonal touches like tinsel, glitter and baubles.
Since 2010, Sport in Mind’s partnership with the NHS has enabled it to help more than 31,000 people struggling with mental health challenges.
It offers sport-based activities to promote physical activity in boosting people’s mood and improving mental health.
Speaking at the launch of the festive campaign, Reading striker Kelvin Ehibhatiomhan said: “We’re very lucky that we have maybe a group of 30 players that we can speak to on a daily basis.
“A lot of people don’t have that type of relationship, so it’s important that they have someone to speak to and organisations like this to make it possible for them.”
