Overview of the New Balance 623

New Balance 623

The New Balance 623 is advertised as a stability walking shoe. It’s meant to provide both cushioning comfort and support for mild overpronators who need help controlling excess inward foot rolling.

This shoe uses a dual-density midsole, meaning it has a firmer density post on the inside of the shoe to prevent pronation. The 623 also employs New Balance’s proprietary ROLLBAR technology, which utilizes a posting system to add stability and support.

The upper of the 623 uses a combination of leather and mesh materials to offer a secure, breathable fit. The shoe has a traditional lace-up closure and padded tongue and collar. Inside, it’s lined with soft fabric to prevent irritation.

Underfoot, this New Balance walking shoe utilizes a durable rubber outsole in a classic walking shoe tread pattern. It provides multi-directional traction and flexibility. The 10mm heel drop promotes a natural foot strike.

Some of the main pros of the 623 are its excellent motion control, cushioning, and comfort. It fits well for those needing a little extra arch support and has a roomy toe box. Potential cons are its heavier weight and stiff feel that may bother some wearers.

Overview of the New Balance 624

The New Balance 624 is described as a cushioned walking and cross training shoe. This versatile athletic shoe works well for a variety of gym activities in addition to walking.

The 624 utilizes a full-length ABZORB midsole, providing exceptionally soft and responsive cushioning underfoot. This proprietary foam compound absorbs impact and diffuses shock for a smooth, comfortable ride.

For stability, the 624 employs TPU posts along the instep to prevent overpronation. The shoe also has a wider outsole platform in the rearfoot to create a stable base of support.

In the upper, a combination of leather and mesh provides a secure, breathable fit. Overlays on the leather offer structure and midfoot support. The traditional lace-up design includes extra eyelets for a customized fit.

Underfoot, the high-quality NDURANCE rubber outsole is made to last. It has a zig-zag tread pattern that allows flexibility in multiple directions. The 12mm offset promotes forward momentum.

Key benefits of the 624 are its soft, plush cushioning and support. It works well for various gym activities in addition to walking. Potential downsides are the break-in period and narrow fit for some wearers.

Key Differences Between the New Balance 623 and 624

While the 623 and 624 share similarities, there are some notable differences between these two popular New Balance models:

1. Midsole Material: Dual Density vs. ABZORB Foam

The New Balance 623 and 624 utilize different materials in their midsoles, which are the cushiony parts of the shoes that absorb shock. The 623 has a dual-density midsole.

This means it has two layers of foam with different levels of firmness, helping to provide a balance between support and cushioning. This feature is particularly helpful for individuals who need stability.

On the other hand, the 624 employs ABZORB foam. This foam is known for its excellent shock absorption and softer feel.

This makes the 624 ideal for those who prioritize comfort and a plush feeling underfoot, especially during activities like walking or gym workouts.

2. Stability Features: ROLLBAR vs. TPU Posts

For stability, a crucial aspect of any shoe, the 623 and 624 are equipped with different technologies. The 623 uses the ROLLBAR posting system.

This technology helps to control rear-foot movement, which is essential for individuals who overpronate (when the foot rolls inward too much). This ensures a safer and more balanced walking or running experience.

In contrast, the 624 features TPU (Thermoplastic Polyurethane) posts along the arch. These posts provide additional support and structure, especially beneficial for neutral walkers and gym-goers who require a stable base for various activities.

3. Weight Considerations: 11.6 oz vs. 12.2 oz

Weight is a significant factor in choosing the right shoe, impacting the wearer’s comfort and endurance. The 624 is slightly lighter, weighing in at 11.6 oz. This can make a difference for people who prefer a lighter shoe, especially during long walks or workouts.

Conversely, the 623 is a bit heavier at 12.2 oz. While this difference might seem small, it can be noticeable during extended use. However, some wearers might prefer the additional weight for added stability and support.

4. Heel to Toe Offset: 10mm vs. 12mm

The heel to toe offset, or drop, can influence how your foot strikes the ground. The 623 has a 10mm drop, which is suitable for mild overpronators who need stability. This design helps in balancing and stabilizing the foot during movement.

In comparison, the 624 has a higher 12mm drop, facilitating forward momentum. This design caters to those who desire a more forward-leaning posture, aiding in propelling the body forward, especially useful for brisk walking or running.

5. Outsole Material: Durable Rubber vs. NDURANCE Rubber

Outsoles, the bottom part of the shoe that contacts the ground, are pivotal for traction and durability. The 623 employs a durable rubber compound, which is robust and reliable for everyday walking.

In contrast, the 624 uses NDURANCE rubber. This type of rubber is renowned for its resistance to abrasion, making it last longer, especially on rough surfaces. It’s particularly beneficial for those who walk on varied terrains or use their shoes heavily in the gym.

6. Usage: Walking Shoe vs. Crossover Walking/Gym Shoe

Both the 623 and 624 are versatile, but they cater to slightly different markets. The 623 is marketed primarily as a walking shoe. It’s designed for individuals who need a stable and supportive shoe for regular walking, especially those who mildly overpronate.

The 624, however, is branded as a crossover walking/gym shoe. Its design accommodates a variety of activities, from walking to gym workouts, offering a versatile option for those who engage in diverse forms of exercise.

7. Fit: True to Size vs. Sizing Up

Fit is a critical factor when selecting a shoe. The 623 generally fits true to size for most wearers, making it a reliable choice without the need for adjustments.

However, the 624 tends to run about 1/2 size small. This means that wearers might need to size up to ensure a comfortable and snug fit, especially important for avoiding discomfort during prolonged periods of wear.

8. Upper Design: Leather/Mesh Upper and Overlays

Both models feature a similar leather/mesh upper, which is the top part of the shoe that wraps around the foot. This design offers breathability and comfort.

However, the 624’s overlays provide a tad more midfoot support and structure. This added feature enhances the shoe’s stability, particularly beneficial for those engaging in various activities.

9. Price Comparison: $65-$85 Range

In terms of pricing, both the 623 and 624 are quite comparable, generally retailing for around $65-$85. However, the 624 might be priced slightly higher in some stores or online platforms due to its additional features and crossover versatility.

This versatility makes it a good investment for those seeking a multi-purpose shoe that can transition between walking and gym activities.
