I bought these and thought they were the right size, tried them out up in the Labyrinth this week and turns out they are one size too small. So they are up for sale.
I wore them for about an hour, on track, took them off. That's the grand total of the use they have had.
I have just washed them with Nikwax, ready to post.
They have large zippers around each boot to enable you to get them on and off with boots on. They are size medium, I stand about 180cm and they are a tad small if you like your pants to hang over your boots, which I do. I would guess 175cm and under would be ideal fit. I will be buying a set in large as soon as these sell.
$130 including postage to Aus.
