Hi Chef23 - just back from 3 days at Mammoth, and I do have some 'observations' regarding MY recent boot move - possible things to look at in your case? I don't know.
so, in this 3day 'session' I did make a move from my Dobbie 130 Pro EDTs to Dobbie 120 Spitfires ( will purchase from friend as opposed to buying new PM 120s...). This, mainly to get a easier flex (have already worked 130s enough to know I still wanted a bit easier flex) for better control in varied terrain/conditions.
I REALLY, really like the way the Dobbie 120s ski ! And they fit just like the Dobbie 130s !!!
but... I did experience 'shin soreness' all 3 days... But NOT sore like 'overwork/pressure', more like 'abrasion soreness'. I mulled this over and over in my head on my rides up in the Gondie - all day Sunday/yesterday...
So what was the difference between the 2 boots ??? had me stumped... especially with the slightly softer flex on the 120s
Long story short - The Dobbie 120's tongue (like the stock 130 Pro EDTs) have a 'faux' leather cover. For 9 years, my 2 pairs of 130 EDTS have had neoprene2 layered over the stock tongue. I compared... Definitely, the stock tongues 'grip' my ski socks (3 diff. ones used in the 3 days) more than the neo2 layer surface... add in whatever effect the long underwear add... And I think I have more 'abrasion' (reddness/soreness due to fabric sliding on the shin) in the Dobbie 120, without the neoprene2 layer...
maybe it's the long underwear??? the ones I used on this trip were different, and slightly heavier than last trip - much colder days...
Haven't really come to a method to 'test' this yet - but will figure something out on my next trip up (hopefully in the next 10 days...)
so, Chef23
... is there a chance the soreness you're feeling is due to some abrasion effect ??? just offering as something to consider ??? don't know...
...I will report back when I get to ski again and determine a 'test' method... I have both boots so, some direct comparison can be made... along with testing the effect of the varied sock and underwear fabric... a lot of variables, but maybe I can come to some reasonable methodology...
