how do you wash them then?

Great find! Now, I can go out in slippers when its raining.

I've had these for over a year and find them better and comfier than my SealSkinz. Just wash as normal with the rest of your gear, turn inside out to dry. I've never needed to use any 'waterproof washes' as I do with my waterproof tops to clean and replenish the outerskins. Since these have no outerskins for waterproofing or beading. The pressure from you feet in the shoes may eventual penetrate through them, normally nicks from toe nails or walking in them in gravel are the causes of waterproof loss. Like I say as good as sealskinz. You can/could also buy this brand more expensively on Amazon, assuming these are still the Dexshell brand as they look the same as the ones they sold last time.

Bargain

Are these better than the ones they sold a few years back for £4.99?

Interesting. Breathable, so shouldn't make your feet sweat.

Thanks will keep an eye out for these.

For washing, use a dwr replenisher like grangers.

You don't need a DWR like Grangers as they have a breathable / waterproof membrane

They are the same ones as on sale two years ago by the way :smiley:
