Our verdict

The Escalante 4 marks a long-awaited return to the series' origins. In our testing, we discovered that Altra has masterfully balanced a spacious zero-drop shoe with a close-to-the-ground running experience. The revamped knit upper is incredibly cozy, though it could benefit from improved ventilation, and the tongue remains non-gusseted. Despite these minor issues, we think it’s a great upgrade, solidifying its status as an ideal choice for minimalist enthusiasts seeking a versatile shoe suitable for running, walking, or cross-training in the gym.

Who should buy

Toebox width - big toe:

  • Zero drop enthusiasts seeking a stable shoe that delivers an awesome ground feel.
  • Those in need of a versatile, low-drop shoe ideal for walking, some gym activities and, of course, running!
  • Loyal fans of the Escalante series who were let down by the previous model, as this version returns to the beloved features of the 1.5.

nbsp; |  

Who should NOT buy

As a zero-drop shoe, the Escalante 4 may not suit runners with recurring Achilles or calf issues. If that's you, we suggest the oz / 194g, which offers a flexible ride paired with a higher drop—ideal for better heel support.

We also found that the upper, while incredibly comfortable, lacks sufficient ventilation for those in warmer climates. However, Altra addresses this with the Escalante Racer, which boasts perfect ventilation and retains a cozy knit upper, solving this issue while preserving the core Escalante DNA.

Cushioning

Heel stack

The Escalante 4 features a heel with a relatively low stack height of just 23.8 mm, at least by today's standards.

Though this may seem low, it's crucial to remember that Altra tailors its shoes with a zero-drop design, so heel cushioning is not that important because most runners should strike the ground with the midfoot or forefoot with this shoe.

The forefoot of the Escalante 4 maintains a similar profile at 22.4 mm, perfect for those seeking a ride that’s a bit cushioned yet still feels very connected to the ground.

Close, the photo below clearly shows what we previously discussed during the outsole thickness test—the rubber is integrated into the foam rather than merely being glued on top.

Drop

We discovered a 1.4-mm heel-to-toe drop in the Escalante 4, which is acceptable for a zero-drop shoe due to slight manufacturing variations or foam compression.

nbsp; |   zero drop

Given this minimal drop, the shoe isn't suited for everyone. Zero-drop footwear caters to those who are comfortable with such an offset. For newcomers to this group, we recommend gradually integrating this shoe into your routine to ease the transition, starting just walking and then gradually increasing running.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Moving to the midsole, we discovered that Altra employs its standard EGO foam, which offers a balance between a firm and balanced feel for us (27.8 HA).

For those who favor plush midsoles, the Escalante 4 won't meet expectations. However, we advise against soft midsoles in low-stack shoes, as softer foam could lead to bottoming out and discomfort. If you're seeking a plush yet low-drop option, the oz / 269g provides a cloud-like ride with a zero-drop design.

Toebox width - widest part

Our expectations were sky-high for the spaciousness of the upper, as the Escalante 4 boasts Altra's Original FootShape—the brand's roomiest toebox design.

That's why we weren't surprised to measure 101.0 mm at the widest part of our gel mold, providing ample room for those blessed(?) with ultra-wide feet.

On the flip side, the Escalante 4 sits fairly low in the toe area at 25.4 mm, though we didn’t find it problematic thanks to its stretchy knit upper. However, if you’re someone who dislikes feeling the upper on your toes, this might be a concern.

Stability

Lateral stability test

One of the key benefits of a shoe that keeps you close to the ground is the immediate increase in stability compared to average running shoes. We can confirm that the Escalante 4 provides a remarkably stable ride for neutral runners.

Torsional rigidity

The Escalante 4 bends and flexes like crazy, scoring a 1/5 from us, which is a crucial component of its natural feel and comfort. And while its flexibility might detract from stability, the low stack height naturally enhances this aspect without necessitating a rigid structure at all.

Flexibility / Stiffness

Returning to the midsole, we measured its dimensions using calipers, starting with the forefoot.

Our initial measurement revealed a very wide platform at 118.3 mm, which undoubtedly contributes to the remarkable secure feel we experienced during landings on our runs.

Discovering a narrow heel measurement of 82.5 mm on the shoe was not a shock to us in the lab. It seems Altra relies on the stability provided by its moderately firm midsole, and low-drop configuration—all tailored to enhance stability and reflect the natural shape of the foot.

This narrower heel may not suit extreme heel strikers though, but it's likely that such runners may have been attracted to the Escalante series, considering that it's a zero-drop shoe.

Weight

While we previously suggested that Altra might consider reducing some weight from the Escalante 4, it’s not something that worries us at all.

At just 8.4 oz (237g), the E4 is remarkably lightweight, although any improvement in the next update would be appreciated here in the lab!

Breathability

The Escalante 4 replaces the mesh upper of its predecessor with a more comfortable knit upper. Initially, we were concerned that, as is common with knit uppers, this change might reduce ventilation. To verify this, we conducted a series of lab tests.

In our initial evaluation with the upper, we employed a smoke-pumping machine to assess the shoe's ventilation capabilities. This test clearly demonstrated that air flow was less effective than we hoped. As a result, we assigned a modest rating of 3 out of 5, indicating that while the shoe provides some ventilation, it falls short of providing optimal breathability.

Using a simple light test, we discovered another significant reason for the reduced ventilation—the knit is much thicker and more structured when compared to the Racer, with reinforced areas in the toebox, arch, and heel to enhance durability and stability.

nbsp; |   microscope

However, to fully understand this issue, we need to use multiple tools. Examining the shoe under a microscope, we found the knit to be extremely cozy, yet lacking in sufficient gaps for air and moisture to escape.

nbsp; |   knit

In our hands-on assessment, we appreciated the upper's stretchiness and how well it conforms to the feet. However, don't expect it to be ultra-padded, as it's clearly designed for being lightweight.

However, it's clear this shoe is best suited for runners who avoid extremely hot conditions.

Outsole hardness

With the upper properly analyzed in terms of durability, we now focused into the outsole. Our first measurement placed the outsole hardness at a rock-solid 86.2 HC, which is notably above average.

nbsp; |   FootPod
If you're looking for a running shoe that flexes in sync with your feet, the INNERFLEX design of the Escalante 4 truly delivers.

Why this choice? Well, Altra FootPod outsole, which resembles a human foot in terms of shape and flexibility, can also wear down quicker than a shoe with full-length rubber coverage.

Outsole durability

The Escalante 4 features an interesting outsole that blends exposed foam with rubberized sections for added toughness and hard rubber in the areas most susceptible to wear.

We were particularly impressed with this design after our latest Dremel test, where the outsole sustained only a 0.3-mm dent. That's an A++ for us!

Outsole thickness

To conclude our analysis of the outsole, we measured its thickness, which registered at a substantial 4.6 mm. However, unlike other shoes that simply layer the outsole over the foam, Altra ingeniously sinks the outsole into the foam.

This innovative approach allows for more rubber without making the shoe cumbersome. However, after observing the toughness of the rubber when it faced our Dremel, we believe that a 4.6 mm thickness is excessive and Altra could benefit from slightly reducing this measurement.

Tongue padding

The tongue of this shoe breaks away from the average design of daily trainers, sporting only 1.5 mm of padding—reminiscent of competition shoes

The lockdown is excellent, yet we still appreciated having the extra eyelet to tie a runner's knot if needed (not for now).

This makes it suitable only for those comfortable with minimal instep padding. Conversely, runners who tighten their laces tightly might face discomfort due to the thin tongue of the Escalante 4. For a cushy option, try the Altra Via Olympus 2, which features a 3.9-mm tongue.

Removable insole

We discovered that removing the insole from the Altra wasn't an issue since it isn't glued down. 

However, due to its distinctively rounded design in the toebox, integrating an insole from a different shoe or custom orthotics may not work well. Oh, and another reason to keep the stock insole is that it's one of the few on the market that is perforated, enhancing the shoe's ventilation.
