1. What are running shoes

Running shoes are sports shoes designed to support the foot during repetitive movements such as running or brisk walking. Compared to lifestyle sneakers, they feature specific construction characteristics:

• midsoles with cushioning materials to manage ground impact;
• outsoles designed for grip and movement;
• uppers in technical materials for lightness and breathability;
• a last shape suited to the forward motion of the foot.

Not all running shoes are the same: there are models designed for road running, trail, gym workouts, walking and mixed everyday use. The differences between these models are real and worth considering when choosing.

2. Running shoes vs lifestyle sneakers

This is a distinction worth making, because many models overlap in aesthetics but not in function.

If you're looking for a shoe for everyday and city use, a sneaker may be the right choice. If you plan on regular physical activity — even light — a running shoe is more appropriate. See also our guide How to Choose the Right Everyday Sneakers for a detailed comparison of the two categories.

3. Intended use: running, walking, gym, everyday

The first criterion to consider is clarifying what you'll actually use the shoes for. The features that matter change depending on the activity.

Light running (jogging, 2–4 times a week)

For moderate-intensity road running you'll want:

• good cushioning to manage repeated ground impact;
• a breathable upper for extended use;
• adequate grip on asphalt;
• a stable but not rigid fit.

Brisk walking

For brisk walking or Nordic walking, cushioning needs are slightly lower than for running, but overall comfort remains the priority:

• a soft but responsive midsole;
• a flexible sole;
• a wide or at least non-narrow toe box.

Gym and indoor training

For the gym, priorities shift: less vertical cushioning, more lateral stability, and a sole suited to indoor floors:

• a flat or low-drop sole for weight training exercises;
• an upper that holds the foot laterally;
• a contained weight for agility.

Mixed or everyday sport use

Many people look for a shoe that works for both light physical activity and everyday wear. In this case:

• a versatile model with medium cushioning;
• a neutral or casual-friendly aesthetic;
• an upper durable enough for varied use.

4. Cushioning

Cushioning refers to the midsole's ability to absorb and distribute ground impact. It's one of the most relevant features in running shoes, but more cushioning doesn't always mean better performance.

• High cushioning: may offer more comfort during longer sessions or for those who prefer a softer underfoot feel. Tends to feel less responsive.
• Medium cushioning: balances comfort and response. Suitable for most non-professional uses.
• Low or minimal cushioning: maximum ground feel, suited to those who prefer a more natural ride. Not the most appropriate choice for beginners.

Midsole materials vary from brand to brand and may include EVA, proprietary technical foams or hybrid combinations. Exact characteristics depend on the model: the product description is the most reliable source for understanding the type of cushioning offered.

5. Sole and grip

The outsole is the part in contact with the ground. It determines grip, durability and adaptability to different surfaces.

• Smooth or semi-rigid sole: for asphalt and hard surfaces. Optimised for rebound and durability on roads.
• Lugged sole: for trail and uneven surfaces. Increases grip on dirt and mud but can be uncomfortable on asphalt.
• Mixed sole: versatile, suited to those who alternate between surfaces.

For most urban and everyday uses — city jogging, gym, walking — a road-oriented sole is sufficient. A trail model is not necessary for those who don't run on natural terrain.

6. Upper and breathability

The upper is the top part of the shoe that wraps around the foot. For running shoes the key characteristics are:

• Technical mesh: the most common material for running shoes. Lightweight and breathable, it adapts well to the foot's profile during movement.
• Structural overlays: reinforcements at specific points (heel, toe, lateral) for stability and durability.
• Padded tongue: reduces pressure on the top of the foot and improves comfort during extended use.
• High or low collar: a low collar offers more freedom of ankle movement; a high collar provides more containment.

If you plan to use the shoe in wet conditions or dusty environments, consider models with more resistant uppers or water-repellent treatments. For everyday use in dry conditions, a standard mesh is the most practical choice.

7. Weight and comfort

The weight of a running shoe can range from under 200 grams for race models to over 350 grams for heavily cushioned or robust ones. For non-professional use, absolute weight matters less than the overall feel on foot.

What matters most for everyday comfort:

• how the shoe feels in the first few minutes of wear (it should not be immediately uncomfortable);
• how weight is distributed across the upper and sole;
• how flexibly the sole bends during push-off;
• heel stability during movement.

A heavier but well-cushioned model can be more comfortable than a light but rigid one — it depends on the use. Neither option is universally better.

8. Sizing and fit

For running shoes, sizing is a critical aspect. Unlike lifestyle sneakers, running shoes may require half a size up compared to your standard everyday size, but this always depends on the brand, model and fit.

The reason is straightforward: during a run, the foot warms up, swells slightly, and slides forward inside the shoe. Having a bit of extra room in front of the toes reduces pressure on the toes during use.

Some general guidelines:

• measure your foot at the end of the day, when it's at its largest;
• consider the type of sock you'll wear with the shoe;
• if you're between two sizes, consider the larger size for running shoes, especially if the product description indicates a narrow fit;
• always check the fit notes in the product description — some models run narrow or wide compared to their stated size.

The values above are indicative. The best choice depends on the specific model, the brand and your foot's characteristics. Always verify the information in the product description.

10. Pre-purchase checklist

Before confirming your order, run through these points:

• Have I clarified what I'll use the shoes for (running, gym, walking, everyday)?
• Have I checked the cushioning type for this model?
• Have I verified the sole type against the surfaces I'll use them on?
• Have I read the fit and sizing notes in the product description?
• Have I considered whether half a size up may be useful, based on the model and fit notes?
• Have I factored in the type of socks I'll be wearing?
• Have I checked the return policy in case the size or fit doesn't work?
• Have I reviewed the information on authenticity, returns and purchase conditions?

12. FAQ

What is the difference between running shoes and sneakers?

Running shoes are built for physical activity: they feature cushioned midsoles, technical uppers and outsoles designed for movement. Lifestyle sneakers are designed for everyday and city use, with less emphasis on technical performance. For a detailed comparison, read our guide How to Choose the Right Everyday Sneakers.

Can I use running shoes at the gym?

It depends on the model. Some running shoes with high cushioning are not ideal for weight training exercises, where a flatter, more stable sole is preferred. Models with a low drop and versatile sole adapt better to mixed use. Check the guidance in the product description.

Should I size up compared to my normal shoes?

It depends on the model and fit. Many running shoes are chosen half a size up to allow enough room at the toe during a run, but this is not a rule that applies to all models. See our guide How to Choose the Right Shoe Size Online and the fit notes in the product description for the model you're considering.

How much do running shoes weigh?

Weight ranges from under 200 grams for race models to over 350 grams for more cushioned or robust ones. For non-professional use, absolute weight matters less than the overall feel on foot. Check the product description for the exact weight of the model you're considering.

How do I choose between high and low cushioning?

For beginners or occasional users, medium cushioning is often a balanced choice: it provides comfort and responsiveness without requiring adaptation. High cushioning may be useful for longer sessions or for those who prefer a softer feel underfoot. Low cushioning suits those who prefer a more natural feel and already have experience.

Can running shoes be worn every day?

Yes, many models are designed for everyday or mixed use as well. In that case, look for a model with a versatile sole, a neutral aesthetic and medium cushioning. Keep in mind that wear increases with frequent use: factor this in when assessing the model's durability.

13. Conclusion

Choosing running shoes online is straightforward once you have a few criteria clear: intended use, cushioning, sole, upper and sizing. You don't need to be an expert to make a good choice — reading the product description carefully and thinking about how you'll actually use the shoes goes a long way.
