The Altra Experience Flow 2 is designed for runners seeking a light and natural feel in their footwear. It delivers a grounded yet energetic ride, enhancing comfort with its square-shaped upper. Verified by our lab testing, it ranks as the top Altra running shoe we’ve evaluated.
The midsole of the Experience Flow 2 adapts smoothly to each stride, while the outsole’s flex points align with foot structure. It requires minimal effort of 10.0N to bend the shoe to 30 degrees, compared to the average of 15.2N. Each stride feels effortless due to its lightweight construction at 8.3 oz (235g), which is 11.3% lighter than average.
In addition to high adaptability, the Experience Flow 2 offers a natural feel with its low platform of 30.3/25.9 mm and minimal drop of 4.4 mm. Despite its compact design, it provides significant springiness, achieving energy return scores of 60.3% in the heel and 68.1% in the forefoot.
The upper is shaped to mimic the natural contours of the foot, especially in the toebox, accommodating both wide and square feet. At 82.6 mm, it is notably 9.3 mm wider than average, allowing for comfort without pressure points.
However, the outsole has been found to be more susceptible to damage compared to typical running shoes. For those prioritizing durability, this may not be the ideal choice.

The Vanish Carbon 2 is an ideal choice for runners seeking a lightweight and responsive shoe that excels in racing conditions. During our runs, we found its airy design to be easy on the legs while maintaining speed. The prominent feature of this shoe is its midsole, which provides energetic takeoffs and gentle landings.
In our assessment, we examined the midsole and discovered two foams separated by a curved, spoon-shaped plate. This design ensures smooth turnover while maintaining flexibility comparable to plateless shoes, enhancing overall comfort. The upper foam pressing against the plate has a firmness rating of 22.8 HA for responsiveness, while the lower layer offers a softer impact with a rating of 9.9 HA.
True to its name, the Vanish Carbon 2 feels almost weightless, registering at just 7.4 oz (210g), which is 20.8% below the average weight for running shoes. It features a modest stack height and a low drop of 3.7 mm. While it is not classified as a zero-drop shoe, the ride maintains a forgiving feel suitable for racing.
Further contributing to the sensation of lightness is the extremely airy upper, which received a perfect score of 5/5 in our lab tests for breathability. Its lightweight design helps prevent hotspots and excessive moisture buildup during runs.
However, it's important to note that the Vanish Carbon 2 may not offer the same level of responsiveness as some other supershoes on the market. Runners focused on maximizing their race times might consider exploring alternatives better suited for that purpose.

The Altra Lone Peak 9 is designed for athletes seeking a reliable zero-drop experience during Spartan races. It offers a grounded and stable sensation, enabling intuitive maneuvering for various exercises, including obstacle climbing and burpees. With ample room for toe splay, it supports natural movement.
This model features a low and firm cushioning system that enhances surface sensitivity, resulting in secure and stable strides. Lab measurements confirm a true zero heel drop, significantly lower than the average of 7.5 mm, along with a balanced 23.6 HA foam measurement, which improves control during multi-directional movements by minimizing uneven compression.
With its wide toebox, the Lone Peak 9 allows freedom of movement, making it suitable for a variety of activities such as lunges and weightlifting. Its square-shaped silhouette provides additional comfort, supported by lab tests showing the big toe area measures an impressive 85.3 mm. This design accommodates natural foot dynamics well.
Users can expect reliable traction from the LP9+ version on both dry and wet surfaces. During testing, we experienced increased confidence while navigating arenas and climbing walls, aided by sticky lugs measuring 3.8 mm deep, strategically positioned to enhance grip.
