Carbon fibre sheet to stiffen soles for crampons?

[kinkyboots]

I hope they work out for you although there are a couple of points you may wish to take into account.

The strength of any boot comes from a combination of the thickness of the leather and the resistance to flex of the sole/midsole. Bear in mind that both the leather and the sole unit will give/flex more than they do now once they are worn in.

Whilst neatsfoot oil (similar to mink oil) is a very good waterproofing treatment it can over soften the leather which sort of defeats the object of what you're actually trying to achieve. You might want to think about sticking to wax treatment in the future and you may find this earlier post useful http://www.walkingforum.co.uk/index.php?topic=39039.msg555671#msg555671

I would recommend that you consider buying and using both the Cherry Blossom Waxed Leather Oil for the high wear areas such as the flex point and tongue and the Grangers G-Wax for all over use as specified in the Whalley Warm & Dry leaflet in that thread. You will find that it's £10 well spent.

It won't do any harm to contact [censored] regarding the crampon compatibility of the Breithorn Pro GTX to see what if anything they recommend. From a safety (covering their a$$) point of view you may well find they don't or won't recommend the use of any crampons.

I hope it doesn't take a genius to work out what word has been censored.

Thank you Kinkyboots for your advice. There must be a dyslexic censor program.
Do you or does anyone else know the difference between grangers g-wax and their waterproof wax?  Both are said to contain bees wax are are waterproofing although the waterproofing wax is more expensive.

Apart from the Waterproofing Wax (100ml jar) being a bit more expensive I think it's a softer wax making it easier to apply and work the oils contained in it down into the leather. It will no doubt have a higher oil content than the G-Wax (80g tin). I haven't used any myself but the Waterproofing Wax looks to be very similar to Meindl Sport Wax. I believe the Grangers Waterproofing Wax was previously branded and sold as Grangers Paste Wax so if you come across any of the Paste Wax for sale it's old stock.
