In reply to George Ormerod:
I’ll give the other side to the coin then… they are utter shite in my experience. Current owner of a pair of Arctic Claws in last legs, and another pair of NVii F1 dobs.
bought for orienteering, replacing a set of Orocs at the time. The Icebug Sprint (Tove Anderson ones??) IIRC lasted approx 90km until they had a massive tear where they separated from the footbed.
The dobs dug into my feet from day 1. Fine in soft forest, brutal on Lakeland or Dales territory. The rubber was inflexible, didn’t have a patter than held latterly in mud, and balled up in snow.
Honestly wish I’d never wasted my money on them. Was happy to bin them when the were utterly unsuitable for training 90km or so later again.
As an aside, why not just look at VJ?
