overboot for insulation

Hi there, someone recommended getting an overboot should you be out on a really cold day.  Anyone else use something like this?

Better off replacing the insole with something better than what comes with the boot.

Can you recommend anything?

I couldn’t open your link but I’ve used Dry Guys Booties for the last few seasons on my single boots.   They def work well and don’t interfere with crampons.  These aren’t a replacement for a legit overboot but work remarkably well on cold days.  Goes without saying...replacing the stock insoles with a Superfeet, Dr Scholls or other neoprene type insole will add warmth as well. 

Overboots add warmth at the cost of added bulk.

What are you using them for?  Climbing?  Hiking?  Also, what kind of boots do you have now?  Where are you located and what type of conditions will you be out in?  Do you do overnight stuff?

Not trying to answer a question with a question.  Can't give a fair answer without further details.

I have had good luck with the Superfeet Red in my boots. There are some similar that are good but I can not remember the brand.

40Below overboots are badass

Thanks Matt, sorry my link didn't work but yes they are Dry Guys.  I will look around for neoprene insole

I'm in the PNW but will heading to Canmore.  Initially the weather called for -10 to -15 celsius so I thought I would buy something in case I do get cold.  I will be doing ice climbing (bit of a newbie) and have the Nepal Evo. 

Overnight will be in the plans in a few years!

Of course you'll be cold in the Nepals. You need to upgrade to double boots like the Sportiva G2SM

Overboots and crampons are like oil and water, they just don't mix well.

In a mountaineering setting, using strap on style crampons (front and back like the BD Contact) is really the only viable way to get a proper fit with overboots, and even then, dropping a crampon is possible. I know some climbers that use semi-automatics with overboots, but again, getting the heal lever to fit nicely is tough. For moderate grade 2 ice strap-ons style crampons will work, but are not ideal, given other options. Front pointing with strap-on crampons sucks. 

For pure ice you want your crampons dead solid on your boots---fully automatic is the way to go. Getting a proper fit with automatic crampons and overboots is difficult and I personally would not climb ice with that combination. At the temps you are expecting, double boots are a better option. You could try experimenting with vapor barrier socks, which will help you squeeze more temperature range out of your singles, but that is another discussion altogether.

Waterfall ice with a single "super gaiter" is fine in the temps he's talking about, -15c isn't even cold for Canmore, that's 5f. 

Our dumbasses did Louise falls at -25c, I had phantom 6k doubles, one partner had baturas (super single) and another had nepal evos.

My feet were sweating and I was glad it was a ladder (tech climbing in doubles sucks imo)
Nepal evo partner got barfies from their feet, but no cold injury (wouldn't recommend it)

The baturas were the goldilocks. 

Overboots are a pain in the ass- not an "in case" sort of thing. They're on or not.

The temps you mentioned aren't that cold.  I routinely ice climb arouns 0 F in singles, odds are that you'll be fine- especially if you're cragging and not too far from the car.

If you think you'll freeze your feet, go with doubled boots as others have already suggested.  Rent plastics or buy something like the G2 or Tech 6000.

Saw this and thought I'd mention my experience in Canmore the past two Februaries.  Temps were between -30 and -38C, so quite cold, and I wore Nepal Evos during both trips without any issues.  With that said I tend to run warm.  At the start of the day I'd crack handwarmers and put them in my boots so that my boots would be warm initially (handwarmers were then used in my gloves during belaying).  Aside from that I would wear puffy pants when belaying to keep my legs warm.  People don't realize how much heat is lost by poor layering of the lower body, which then can add to the cold issues with feet.  So do you need warmer boots, not necessarily.

Tagging on to this, keep your boots off the floorboard when you're driving, ESPECIALLY in the back seat. The steel body gets extremely cold in those temps and most vehicles HVAC systems really don't channel any hot air down there and it's an ice box. We found leaving boots on top of the back seat kept them significantly warmer. 

Driving back in -30c I had a bottle of water that I left on the rear floor of my car. It was frozen solid a couple hours into the trip, even though it was warm on top of the back seat and I was toasty in just a sweater.

Second this. Winter ascent Whitney and regular ascent Denali, didn’t even think about my feet. The gaiter material is a little flimsy though.
