I have a pair of 345's and previously I had 295's. I got the 345's as they were low boots rather than the trainer style of the 295's this gives some padding to the ankle bones. I think I must have sticky out ankle bones because I do tend to catch them on rocks and roots. Also I trashed the 295's on a trip to Knoydart last year, ripping the uppers quite badly.
I've not had that much use out of the 345's yet, the last time I was out in very wet conditions I was wearing ski touring boots that was the weekend before lockdown. I find them very comfortable and hold the foot better than the 295's, less rolling of the foot. But I suppose that very much depends on the shape of your foot. The previous incarnation of Inov8 boots had very soft rubber in the soles so they wore out very quickly, these (the 345's) are supposed to have some harder wearing compound to counter this, only time will tell if it works.
As I said I've not used them very much only half a dozen days out in the Ochil's and so far they have been dry. Not been in any deep bogs, not had water over the tops so can't say how quickly they will dry out once the inside is wet. This is something that did concern me when I brought them. Having had other gore-tex lined boots I've always found the liners prevent the water from getting out so the boots take forever to dry, again only time will tell.
Underfoot you do get a bit more feel for the ground, not as much as in the 295's which were very thin soled. I find this better than wearing very stiff soled traditional mountaineering boots which can make your gate very clumsy and awkward. It's a compromise, the 295's were very thin but you felt every stone. The 345's are a bit stiffer but still let your foot flex, the only way to tell if it suits you is to try them.
If you plan doing a lot of bog trotting then gaiters would be a good idea, I'm not sure which gaiters would fit best maybe something like the "Dirty girl" gaiters.
