Built for the
Good Yuck out there.
Waterproof from the ground up
One-piece EVA shell. Waterproof from the sole up to where the cuff meets it. Mud, slush, puddles. Welcome to it.
Light upper, no break-in
Lightweight synthetic that looks the part without the bulk or break-in. Easy to wipe, easier to wear.
Shearling that stays put
Plush, warm, sewn in. Nothing to pull out, nothing to lose. Step in, you're good.
One strap, done
One strap, one motion. Snug the cuff, walk. Faster than slip-ons, snugger than laces.
Barely there
Slim enough to disappear under jeans or vanish into a tote. The boot that doesn't announce itself.
Borrowed from the classics
Borrowed from the boots we grew up on. Apres-ski meets school-run, with the kind of look that says you know.

Why we built them
from foam
Most boots in this category are leather or rubber over an insulating layer. We made the whole thing from closed-cell EVA: the same foam in your sneakers' midsole, but molded into a complete boot. Here's what that buys you.
- Lighter. Most boots in this category are 2 to 3 lbs each. Ours don't ask that of your legs.
- Warmer per ounce. Closed-cell EVA traps air. Air doesn't conduct cold. The math works out.
- Naturally waterproof. No DWR coating to wear off, no leather to crack. The shell is sealed because that's how foam works.
- Doesn't crack in cold. Leather stiffens. Rubber gets brittle. EVA stays flexible at -20°F.
- Doesn't get heavy when wet. It doesn't absorb water. It doesn't gain weight.
- Easier to clean. Garden hose. Done.
Almost every other boot in this category is built differently. We're not saying ours is the only way. We're saying it's the way that doesn't ask anything of you.
Nothing
to think
about
Sidekick is the boot you don't think about. That's by design. Two decisions make it work: a permanently-attached faux shearling liner (warm without the laundry) and a single velcro strap (snug without the laces).
- Built-in faux shearling. Plush, warm, soft from the first wear. No liner to lose, no break-in.
- Single velcro strap. One motion to cinch, one motion to release. Faster than slip-ons, snugger than laces.
- Slim profile. Fits under jeans, slides into a tote. The boot that doesn't announce itself.
- +15°F warmth. Plenty for the in-between weeks. Drive to the lift, school drop-off, dog walk, errands.
If Hi Flyer is the deep-winter workhorse, Sidekick is the boot you keep by the door.
The boot you
grab without
thinking
Quick on, quick off, quick out the door. Built for the in-between days. 15°F to 55°F, and everything that isn't quite winter.
Easiest in / out
Velcro cuff, one motion. Faster than slip-ons, snugger than laces. The boot that doesn't slow you down.
One strap
Slim profile
Fits under jeans, vanishes into a tote, looks right anywhere. The boot that knows its place. And yours.
Low-proCommon questions
The stuff people actually email us about.
What size should I order?
+
Measure your foot. Stand on a piece of paper with your heel against a wall, mark the tip of your longest toe, measure the distance in inches. Match that to our size chart. Don't guess by your usual sneaker size. Our boots are unisex sized: the chart shows men's and women's columns side by side because the same physical boot fits both. If you fall between sizes, see the half-size question below.
Do they run small or big?
+
They run true to our size chart. The chart is the boss, not your usual sneaker number. Half the customers who get the wrong size on the first try were guessing instead of measuring. So: measure your foot (see above), trust the number you wrote down, and resist the urge to be clever.
I'm between sizes. Up or down?
+
Size down. Our liner is built thick and breaks in after a few wears, so a snug-not-squished fit out of the box settles to just-right. Going up is where heel slip comes from: if your heel feels slippy after a few wears, you went a step too big. Order the smaller of the two, and exchange free within 30 days if it's not quite right.
Do they fit wide feet?
+
Yes, with caveats. The EVA shell is naturally roomy through the forefoot and doesn't compress around the sides the way leather does. Customers with bunions, wide forefeet, and EE/EEE width feet generally find them comfortable. EEEE+ width, we can't promise, but our 30-day return policy means it's a safe try.
Are they stiff to walk in?
+
The Sidekick is our lightest boot and the most flexible. It's built for the in-and-out winter days, not the deep-snow grind, so flex and ease-of-movement were front of mind from the first sketch.
How warm are they?
+
Less about one number, more about staying comfortable across a wide range, roughly +15°F to +55°F. The cold rating gets the headlines, but the EVA insulates without cooking your feet, so these hold up from deep winter through mud season and shoulder weather. (Assumes a sock, the liner in, and you moving around.) Customers wear them for snow shoveling, dog walks, eight-hour outdoor shifts, and the school run when the forecast can't decide which side of the bed to get out of.
Are they waterproof?
+
Yes. We couldn't bear the name of one of nature's most waterproof birds if we weren't. The EVA shell doesn't absorb water, and the cinch cuff keeps snow and slush out. Wet snow, slush, puddles, spring rain. All fine. Walk across a river and the boots will float; we still recommend not doing that.
Can I buy replacement liners?
+
Yes. Liners are sold separately and size-matched to your boot (shop liners). A lot of customers buy a second pair so they can rotate liners for drying. If your dog chewed yours (it happens, we get the emails), email hello@loonr.com with a photo, we'll figure something out.
How long does shipping take?
+
Most orders ship within 1 to 2 business days. Standard ground delivery is 3 to 7 business days within the continental US after that. We'll send a tracking number when your order ships. All boots ship free. Smaller items (replacement liners, parts) ship at a flat $12.99. Note: discount codes don't stack with free shipping on the same order.
Returns and exchanges?
+
You have 30 days from your order date. Returns and exchanges are free, both ways. Boots should be unworn, or worn only enough to figure out the fit (a couple of indoor laps around the house counts; a snowy outdoor walk doesn't). Start a return at our Returns & Exchanges page. We'll walk you through the steps. Refunds hit your card 5 to 10 business days after we receive the return. Exchanges ship as soon as we process the inbound. No fee, no catch.
From the Van
We started this in a muddy parking lot.
March 2024
Silverton, Colorado
It started with a van. Mud season. Two pairs of unfussy winter boots we'd brought back from Japan that quietly became the company.
In early 2026 we went back. Different season, different reason. We weren't looking for another boot. We found one anyway. Lighter, softer, made for the days that aren't quite winter.
The Sidekick is the boot we fell for on that second trip. The one we made for everything in between.

Probably, yes.

Measure your foot, not your guess.
Stand on a piece of paper, heel against a wall. Mark the tip of your longest toe, then measure heel to mark. Match that number to the chart. Our boots are unisex, so the M and W labels are the same boot with different numbers. Between sizes? Size down.
Snug is good. The liner breaks in after a few wears, so a snug-not-squished fit out of the box settles to just-right. And measure at the end of the day, when your feet are at their biggest.
Still on the fence? Email hello@loonr.com with your measurement and we'll point you to the right pair.
The Yuckproof Guarantee
+
12-month manufacturer's warranty on any boot that fails before you do. Covers cracking, separating soles, broken cinch hardware, busted liners, leaks. Does not cover dogs. Does not cover lawnmowers. Submit a photo with your order number, we'll sort it. Read the full guarantee →
Caring for the boots
+
Spray the EVA with the garden hose. Liner washes cold on the gentle cycle, lays flat to dry. Don't put the liner in the dryer. Don't store the boot near a heater. Don't stage your boots on the front step in July sun for the gram (the color holds up but UV is not their friend). Read the full care guide →
