In my opinion numbness in foot should not be ignored and should be further investigated.
There are chances that their is nerve compression/sciatica/lumbar radiculopathy causing numbness in foot.
It can be related to alcohol intake.
Vitamin B 12 deficiency
Exposure to cold
A clinical examination is required for further diagnosis and management.
X-Ray/MRI of the spine may be useful.
I hope this helps
