Xero Shoes Zero HFS 2 Review: A Tougher Take on the Minimal Running Shoe

Introduction

The Zero HFS 2 is the second version of Xero Shoes’ standard performance running shoe. It keeps the formula that made the original appealing: zero-millimeter drop, a wider toe box, and a more anatomic last. What is new is a tougher build and a more secure upper, both of which address the small compromises of the previous version.

After around 20 miles of short one-to-two-mile runs, gym sessions, and everyday walking, the HFS 2 comes across as a genuinely versatile minimal shoe that retains the barefoot feel while adding a touch of protection.

Who This Product Is For

This shoe suits two broad groups. The first is runners who want a minimal shoe for foot strengthening and proprioceptive work, ideally run in shorter sessions rather than long mileage days. The second is anyone looking for a comfortable everyday shoe, since there is good evidence to suggest that simply walking in minimal shoes or barefoot can be as effective as doing foot-specific strengthening exercises.

It also works well in the gym. The grip holds up to side-to-side movement better than many dedicated running shoes, so it handles varied training without complaint.

Main Strengths

The headline spec is a 12-millimeter stack height with zero millimeter drop, and that stack measurement includes the insole. Remove the insole and you sit even lower to the ground, which is a nice option for purists.

The tougher midsole is the other clear win. The previous version was already durable, but this one feels more secure, with a slightly higher stack and more overlays contributing to a sturdier overall feel.

The upper is where the HFS 2 improves most over its predecessor. The original required gripping the laces down hard to get a secure fit. This version adds more overlays that lock the foot down noticeably better, so a normal lace tension delivers a secure ride without overtightening.

Fit and Sizing

Fit is true to size, and the recommendation is firm: do not go up or down a size. The shoe retains plenty of room in the toe box while fitting snugly through the midfoot.

One caveat: if you are between sizes, going up may be worth testing, because the toe guard can make the shoe feel slightly short for some wearers. Trying them on when possible is the safest route.

Everyday Use and Foot Health

Beyond running, the HFS 2 doubles as an excellent walking shoe and general-purpose trainer. It handles gym work comfortably, with grip that supports lateral movement rather than being tuned only for forward motion.

For anyone interested in foot strength, the case is compelling: walking in minimal shoes like these may deliver benefits comparable to dedicated foot exercises, all while feeling like barely wearing a shoe at all.

Things to Consider Before Buying

The weight has crept up slightly. A size 10 in the previous version came in at eight ounces, and the HFS 2 measures 8.8 ounces. The added weight comes from the tougher midsole, a touch more stack height, and the extra overlays up top. That is a fair trade for durability and security, but minimal-shoe enthusiasts who prioritize featherweight feel should be aware.

Buying Advice

If you want a minimal running shoe with a teeny bit of protection but a genuine barefoot feel, the HFS 2 is an easy recommendation. It is equally convincing as a do-anything walking and gym shoe.

Given that the previous version never wore out despite miles of use, the tougher construction here should only extend that lifespan. Buy it true to size, test it with short runs first, and let your feet adapt gradually if you are new to zero-drop footwear.

Conclusion

The Zero HFS 2 refines an already solid minimal shoe: tougher materials, a more secure upper, and the same zero-drop, wide-toe-box foundation. If you value ground feel, foot strength, and versatility across running, walking, and gym work, this version makes the case better than ever.
