Frequently Asked Questions
Does ultrasonic actually work on ticks?
Does ultrasonic actually work on ticks?
This is the most common worry we hear, and it's an honest one. Here's what we've learned from thousands of customers: the cushioning and support you've been wearing has been weakening your feet for years, which is part of why the pain keeps coming back. Northbound lets your foot move and rebuild the way it was designed to, while the protective sole keeps you safe from sharp objects and rough ground. Start slow. Wear them an hour or two a day at first. Most people notice real relief within 2 to 4 weeks. We include a free Transition Guide that walks you through it step by step.
Is it safe for babies, kids, and pregnant women?
Is it safe for babies, kids, and pregnant women?
Because everything you've tried added more support to feet that were already getting weaker from too much support. Northbound is the opposite approach. We're not asking you to believe in a miracle. We're asking you to give your feet a chance to do what they were built to do. If they don't, send them back within 60 days and we'll refund you. No hassle, no restocking fee, no fight.

We recommend ordering your usual US size. The toe box is wider than a conventional sandal, so you don't need to size up for room. If you're between sizes or have particularly wide feet, size up half a size. And if the fit isn't right, our exchanges are free.
How does the 99-day guarantee work?
How does the 99-day guarantee work?
That's exactly why we designed Northbound the way we did. Most barefoot sandals look strange because they expose every toe or use a thong between your big toe. Northbound looks like a normal, attractive sport sandal you'd see at any outdoor store. The benefits are barefoot. The aesthetic is classic.
How long does the battery last?
How long does the battery last?
Sixty days from delivery. Wear them in your house, walk around the block, test them at work. If your feet don't feel noticeably better, send them back for a full refund. We pay return shipping in the US. We're confident because they work.
The Science
PULSE™ emits a 9–21 kHz wide-frequency ultrasonic pulse designed to disturb ticks, mosquitoes, and other biting insects before they latch on. The frequency operates outside the typical range of human hearing — most adults can't hear it. Dogs and cats, despite hearing higher than humans, are not disturbed at the calibrated intensity.
3 Simple Steps
1. Charge it. 1–2 hours via USB-C — same cable as your phone.
2. Clip it on. Backpack, belt loop, hat brim, shoelace, kid's shirt.
3. Long-press to power on. A small indicator confirms it's running.
That's it. Recharge every 2–4 days.
Tested & Designed Safe
No chemicals to absorb through skin. No fumes to inhale. No radiation. Built-in battery protection and an automatic sleep mode mean it's safe to toss in a backpack, glove compartment, or carry-on.
Designed as an added layer of protection alongside tick checks and CDC-recommended tick-bite prevention guidance.
