Your experiences (I appreciate they're relatively new!) please, and also some places to buy them. A google search only came up with one place, which seems a good one, but if I can find em cheaper, all the better!!

Mine arrived in the post an hour ago
First impressions - they are a really neat fit and seem a lot lighter than the original Old Macs. Horse has been up and down steep slippy stony driveway and the traction was good.

I bought them from Lucy at http://www.thesaddleryshop.co.uk/index.php/cPath/296

They have a hire option for all sorts of boots and are very helpful generally.

Thanks Mandy! It's the saddlery shop that came up with my google search. Didn't see the hire option, so I'll have another look! Ta muchly.
