Lowa tibet gtx and other gear for upcoming trip

Picked up a pair of Lowa Tibet GTX goretex in leather and was wondering if anyone else can attest to their worthiness and also give me an idea of how cold of a temp I can go in them without losing toes.

Well there are just leather burly hiking boots (no insulation), not mountaineering boots.

So the cold rating really depends how your circulation, foot fit in the boots, sock system, your other layers....etc...etc...

...what as said above! Tell us more where you’ll use them and for what intended activity?

Plan on taking them to NH for a weekend Ice climbing trip first weekend of February.

These?

Not made for ice climbing I'm afraid. 

I use the Lowa Camino (very similar to the Tibet’s). With a good pair of socks and while I’m active, I’m comfortable in them down to 5F or so, but my feet typically run hot. Stationary, I would rather have something insulated when it’s below 15F. They’d be fine for light glacier use, but I wouldn’t use them for anything vertical.

Gear including mountaineering boots will be provided so I'll only be wearing these when not actually climbing.  Thanks for the valuable input and good thing Fox Mountain Guides has me covered.

I will be looking for a mountaineering boot in the future as I'm taking ice climbing as a very early step of many many steps to achieve my larger goal of Alpine Mountaineering.

I have very little experience with extreme cold weather gear as I was born and raised in South Carolina.

So far for my trip I've accumulated a Mountain equipment lhoste shell and skyline hoodie, Patagonia simul alpine pants, merino wool base layer and glove liners, and BD terminator gloves.  Do you guys think that's a good start?

The rest of my your kit seems pretty good! Make sure your merino base layer is 250 weight not 150 (via smartwool specs). Depending on where you’ll be climbing - if there’s a long approach - I sometimes will actually switch to a dry base layer to climb. Oh, important - a nice down puffy for belays or standing around.

It's a reasonable place to start. 

One important thing I think you're missing is an active midlayer. Fleece or breathable synthetic.

A softshell wouldn't hurt, but you can start with that Lhotse shell and see where it takes you. 

The Skyline is on the lightweight side for a Northeast belay jacket. I suspect you'll be cold if that's all you're bringing for sitting around outside. 

Gloves. Terminators are a little cold on my hands for most days in the Northeast, prefer Punishers. Some people run warmer. Having at least one pair of extra climbing gloves would be optimal (they get wet/cold), and some big mitts to warm your hands up when you're not climbing.
