A reverend has made a desperate plea for help after seeing "more cases of trench foot in one year" in Lincoln's homeless than in the 27 years he served as a soldier.
Reverend Jeremy Cullimore believes rising heating costs coupled with a lack of donations could see St Mary le Wigford church struggle to help the homeless.
He hopes the public can step in with donations as winter weather increases pressure on the service and puts the health of rough sleepers at risk.
"If someone donated 1,000 pairs of socks to us, it would not last more than a few days," Mr Cullimore said.
"A pair is worn out quickly, that's how rough they live."
He believes the BeAttitude project, which supports Lincoln's homeless, could be forced to cut back on the number of people it helps if rising costs continue.
"The church has no income except from our café and a few grants, so we depend on donations," he explained.
"We give out 30 to 40 morning meals and 40 to 50 evening meals a day. For some of our clients we are the only network they have.
"In addition to food and clothing we offer training and volunteering opportunities to help people back to work.
"Unfortunately it all costs a lot of money to run."
The project helps around 170 homeless and vulnerable people each week with food, drinks and friendly support.
Last month the vicar revealed how desperate modern day slaves have previously sought sanctuary in his Lincoln church.
He told the Echo that since January, six people had escaped slavery and some had found refuge with the church, after being held as slaves.
