Castleberg Outdoors in the UK has just posted a video review of S-Lab Sense 3 Ultra Soft Ground. I first saw and posted about this deeply lugged version of the Sense at this past summer's Outdoor Retailer. Looks like a great choice for snow and mud running.
Castleberg is saying they will have limited stock in January. I have ordered from Castleberg in the past and it has been a smooth and fairly reasonably priced way to buy product not yet available in the US. Not sure yet if US retailers will have January stock but suspect some may.
