Blooming heck,
just get some normal , steel toe capped boots around £20.. put some thermal socks on and you will be fine.
we dont work in the arctic.....
you will be fine with decent gloves and decent warm workwear.
Apart from last winter we only get the same amount of wet days in winter as we do in summer... and an odd frost bitten morning here and there.
After 10am its fine every day.
