Jalette Jalnevis for offshore: like carpet slippers when walking on grating all day long, plus excellent grip on oily surfaces and anti-static etc. Downside, very expensive!
Jalette Jalaska for Construction: Very confortable and I think some places are knocking out for around £45 now.
If you're using them for scaffolding in though, make sure you buy the ones with the external rubber toe protector or they will last about 3 months before they get chewed up!
I can't get on with Red Wings, but the ones they issue out here look like cowboy boots and take forever to break in. Very good quality but also very pricey!
Cheers,
Phil.
