I have a reasonably new pair of Nordica boots that the heel has worn down to the screw. the part is replaceable. I tried to order from the Nordica web site but no joy.  

I would think this should be easy to order on line but lost in the web..... Ideas?

Never bought from these folks they're in UK. They popped up when I was looking for some Salomon pads last year.

Can your local bootfitter help? 

I found a ski shop that had the sole replacement parts in stock when I had a similar problem a few years ago.  Took a while because I had an older model of Nordica boots.  Ended up getting them at Snowbasin.

Might be able to find a set of used boots same model on eBay cheap to cannibalize for parts.  If you boot up at the parking lot I hihgly recommend getting something to cover your boot soles... boots lill last a LOT longer and you won't be busting your butt on icy spots.  There are much better options available than the old plastic cat tracks of the 80s.. 

Thanks guys. Contacted Nordica and they sent me the parts! Back in action!
