Most modern running shoes add more between you and the ground. The Xero Shoes HFS II does the opposite – and it expects you to be strong enough to run in it.
I’ve been training in the HFSÂ Original and the HFS II for more than 5 years, running upwards of 90 kilometres per week and racing in Parkruns right up to the marathon distance – my last marathon in the HFS II was completed in a 3-hour 25-minute marathon at age 59.
That matters because many lightweight shoes feel good at first but don’t hold up once training load increases. My HFS II have proven to be reliable road-running shoes first and foremost, not just something that looks minimal. They fit within a simple setup I use: a dedicated road-running shoe, a separate trail or hiking shoe, and a pair of sandals. The HFS II is not trying to do everything – and that’s exactly why it works so well for running.
If you already run in minimalist-style shoes, this is one of the most capable road shoes I’ve used. If you’re coming from cushioned or carbon-plated shoes, you can swap across to the HFS II – but only if you’re willing to reset your expectations, reduce your training load, and give your body time to adapt.
The fact that they are lightweight and easy to pack makes it practical for my travels, but that’s a bonus – not the reason to choose them. In this review, I’ll show you exactly where the HFS II performs well, where it falls short, and whether it might just be the right shoe for you.

Quick Verdict
The Xero Shoes HFS II is a capable road-running shoe for experienced minimalist-shoe runners who want something light, flexible, and reliable for consistent training.Â
Who It’s For
- Runners who are comfortable in barefoot or zero-drop shoes
- Those with strong feet, calves, and stable running mechanics
- Runners looking for a lightweight road shoe for regular training
- Anyone who values ground feel over cushioning
- Travellers who want a running shoe that is easy to pack (as a secondary benefit).
Who It’s Not For (Without Adjustment)
- Runners currently relying on carbon-plated or highly cushioned shoes
- Anyone expecting immediate performance at previous training levels
- Runners who switch between cushioned shoes and minimalist shoes
- Those looking for shock absorption or protection from the shoe.
Transitioning from cushioned, full-support running shoes to the Xero Shoes HFS II will require some adjustment
Limitations and What to Be Aware Of
The biggest limitation isn’t the shoe – it’s the adaptation required. The Xero Shoes HFS II does not compensate for weak mechanics, poor form, or lack of lower-leg strength. If you are coming from cushioned or carbon-plated shoes, you should not maintain your current training volume or intensity. You will injure yourself.
You will need to reduce your running load, remove performance goals in the short term, and give your body time to adapt. In my experience with athletes I coach, that process can take anywhere from 3 to 12 months. It took me close to 12 months before I could comfortably run around 70 kilometres per week without pain or stress.
Switching between cushioned and minimalist shoes during this period will slow adaptation and increase the risk of injury. If you’re not prepared to adjust your training and rebuild gradually, this type of shoe will not work for you.

HFS vs HFS II: What Actually Changed
The original Xero Shoes HFS built a strong following for a reason. It was simple, lightweight, and delivered a very direct barefoot feel. Xero Shoes didn’t replace it. They kept it. That tells you something. The Xero Shoes HFS II was not a complete redesign. It was a practical update focused on usability rather than changing the core experience.
The Key Difference: Grip and Confidence
The biggest change I’ve noticed is the outsole.
- HFS (original): lighter, more minimal, but less grip—especially on smoother or slightly wet surfaces
- HFS II: improved grip and a more secure feel underfoot
That difference matters more than it sounds. It’s the reason I’ve continued using the HFS II.
What Stayed the Same
- Zero drop platform
- Flexible, foot-shaped design
- Close-to-ground feel
- Lightweight construction
This still feels like the same shoe at its core.
What You Trade Off
You don’t get something for nothing. The HFS II feels slightly less pure than the original. You lose a small amount of that ultra-minimal, barely-there feel. For some runners, that matters.
Which One Should You Choose?
Choose the HFS II if:
- You want better grip and a more secure ride
- You run regularly on pavement or mixed urban surfaces
- You value consistency over the most minimal possible feel
Choose the original HFS if:
- You prioritise maximum ground feel
- You prefer the lightest, simplest version of the shoe
- You already liked and trusted the original design
Bottom Line
The HFS II is not a replacement for the original—it’s the more practical version of it. I’ve stayed with the HFS II because the added grip makes it more usable day-to-day, especially at higher training volumes. If you already run in the original and are happy with it, there’s no urgency to switch. But if you want a bit more confidence underfoot without losing the core barefoot experience, the HFS II is the better choice.

Recommended Running Books
Check out my recommended books that support or promote minimalist running styles and shoes.
- Older Yet Faster by Keith Bateman—Do you want to learn how to run correctly in minimalist running shoes? Keith Bateman's book, Older Yet Faster, is an evidence-based manual that delivers the results many of us are after. With his prescribed minimalist running technique, Keith's M55 age-group world records demonstrate that you can run faster as you age.
- Born to Run by Christopher McDougall – A tale that is both gripping and energising for all who aspire to run the perfect race. And in the end, you are pulled into the characters' emotions as they race through the desert. Nothing will if this book doesn't make you want to lace up afterwards and at least go for a jog.
- Born to Run 2 by Christopher McDougall and Eric Orton—If the original Born to Run book whets your appetite for running in the mountains of Mexico and elsewhere and gives you the WHY, Born To Run 2 gets into the nitty-gritty of HOW to run. It is refreshing to hear new anecdotes, tips, and the answers to how to do it.
- Run For Life by Roy Wallack: I appreciated its practical advice, personal anecdotes, and expert insights, which made it accessible to runners of all levels. The book covers technique, training, nutrition, and injury prevention. It also offers valuable tips on longevity and maintaining a running lifestyle. While its broad scope may lack depth, it is an informative and motivating guide for lifelong runners.
- ChiRunning by Danny Dreyer—This book offers a unique and innovative approach to running. I appreciated its focus on form, injury prevention, and the integration of Tai Chi principles. The techniques helped me improve my running efficiency and reduce pain, although parts of the method took me a while to master.
- Running Injury-Free by Joe Ellis - The book delivers on its promise: practical advice on preventing and treating running injuries. I appreciated its clear explanations and helpful illustrations. It is an essential resource for runners of all levels, though it could include more recent research.
- Pose Method of Running by Nicholas Romanov—Similar to Chi Running, the innovative techniques in this book focus on improving running form and efficiency. This method is specifically effective in reducing injuries and enhancing performance. It requires significant practice to master, and I wish it had more practical examples and illustrations.
- Why We Run by Bernd Heinrich combines science, personal anecdotes, and philosophical insights. Heinrich offers an insightful exploration of the physiological and psychological aspects of running. The book is inspiring and thought-provoking, though I wish it had a more structured narrative to make it easier to read.
- The Minimalist Runner by Nicholas Pang—Though a little older, this book still provides easy-to-understand insights into minimalist running techniques. The chapters on practical tips for transitioning to minimalist shoes and improving form were valuable, if not a little simple. The book is concise and accessible, though it could use more in-depth coverage of training plans and injury prevention.

Where to Buy (Australia and New Zealand)
If you’re based in Australia or New Zealand, buying locally is usually the simplest option. You’ll avoid high international shipping costs and potential delays, and make returns easier if sizing isn’t right.
Here are the main options I use:
- Xero Shoes Australia
- Roam Barefoot (in New Zealand)
Availability and sizing can vary, so it’s worth checking all three.
Buying Direct from Xero (US/EU)
You can also buy directly from Xero Shoes. Pricing is often competitive, but once you add international shipping, the total cost can increase significantly.
If you’re outside the US, I’d only recommend this if:
- Your size isn’t available locally
- There’s a meaningful price difference after shipping
- You’re confident in your sizing.
Is the Xero Shoes HFS II the Right Barefoot Running Shoe for You?
If you already run in barefoot shoes, the HFS II is a reliable road option proven through consistent training and racing. If you’re transitioning, expect to take time and rebuild gradually.
