Just as many will appear in their end of line sales. I'd guess that they have their business folks looking at the sales figures and ROI for all of their new products. Some very will likely have a short lifespan.
It could be the end of the road for these boots. The inner toe box lining has given way and something that feels like a bit of plastic is now digging into my toes. I'll take them to my favourite boot doctor and see what they say and see how much it will cost. They have had a good innings and if it's a reasonable cost repair I will keep them, otherwise they will have to go and I'll look for a new pair of RMW.
Physically, they look in pretty good condition. Soled look to have some mileage left and the leather will respond nicely to some conditioner and polish. Size 9 UK and regular width.$89 after shipping, which for me would be a little high for a well used shoe, but I'm a little fussy about what I put my feet in. Maybe make a lower offer.
