Nebulus
Sneaker ROYAL

In our test, the ROYAL trainers from the Nebulus brand proved to be the ideal companion for everyday summer wear, making a very good impression. The stylish trainers in a stylish design are available in nine differentcolour combinations and different sizes for men and women. For our test, we received the shoes in white and black in size 42 for men and size 38 for women. They proved to be very comfortable with socks. The quality and workmanship are just as impressive as the trainers in the practical test. This shows that the trainers are not only extremely breathable , but also offer good support and feel comfortable even when worn for long periods. However, due to the thin material, the shoes are not suitable for low temperatures. This makes the shoes ideal everyday companions for hot summer days.

Advantages

✅ High wearing comfort with socks
✅ Good workmanship and quality
✅ Thin, breathable material
✅ Effective tread for good traction
✅ Low weight

Disadvantages

❌ Rough inside without socks
❌ Only for high temperatures

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

ROYAL trainers in their product packaging

In our case, the ROYAL trainers from Nebulus were delivered together with other products in a sturdy shipping box. The shipping box was undamaged and could be easily opened with a knife or scissors. The shipping box was also optimally sized as it was filled to the top. This protects the environment : not only is the amount of material required for the shipping box minimised, but the small space required by the package also ensures better utilisation of the transport vehicles. Inside the box were the ROYAL trainers in their product packaging.
The product packaging is an opaque plastic bag with Nebulus print on both sides. The bag can be opened at the top with a resealable fastener. If the shoes need to be returned, the bag can be reused for this purpose.
The bag is also labelled with warnings about the risk of suffocation. Although the warnings are only in English, the dangers are also illustrated with understandable symbol images. On the opposite side there is a sticker showing the product name, colour and size of the shoes. The inside of the shoes is lined with tissue paper to keep them in shape.
The shipping box, plastic bag and tissue paper protect the ROYAL trainers very well from damage and soiling.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

*The maximum score is 100 points

As you would expect, the ROYAL trainers do not require any additional accessories and are supplied without them. The laces are already threaded into the eyelets. On one of the shoes there is a cardboard disc the size of a beer mat, which is printed with the Nebulus logo on both sides in high gloss, as can also be found on the product packaging.
There are no instructions for use, but they are not required. A label is sewn onto the inside of the shoe tongue, which provides information about the manufacturer, the place of production and the material composition.

Women’s version of the ROYAL trainers

There are nine different colour combinations to choose from for the ROYAL trainers. For our test, we received the trainers for both men and women in a white and black combination. The shoes are typical trainers with an elasticated sole and a fabric upper.
The fabric of the upper and the side edges of the sole are white. The underside of the sole, on the other hand, is black, as are the laces and a wide decorative strip on the side surface below the heel. The shoes are also decorated with a pattern on the upper and two discreet Nebulus letterings on the tongue and the back. Overall, the trainers look elegant and stylish thanks to the white colour combination.
The fabric of the construction is strikingly thin. While the inside is made of a uniform weave, the outside features sophisticated embroidery that creates three-dimensional patterns on the fabric. Another special feature is that the tongue is firmly sewn to the side panels along its entire length. The laces are threaded through fabric loops provided for this purpose and lie parallel to each other. The shoe sole is made of smooth rubber and has a slight tread pattern with two deep indentations. It is thin at the front and becomes increasingly thicker towards the back.
In the online shop, the upper material is only imprecisely described as textile , while polyurethane is stated as the sole material. Despite the thin material, the shoe fabric is tear-resistant and hardly stretchable. The seams are also neatly finished and stable. The good workmanship and high quality suggest a long service life.
Overall, the trainers make a high-quality impression despite the thin fabric. The quality of the fabrics used and the seams as well as the overall workmanship are also impressive.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

Weighting: 40%
*The maximum score is 100 points

The ROYAL trainers from Nebulus are promising companions for warm summer days thanks to their thin fabric. In our practical test, the ventilation also proved to be excellent. The breathable material inside the shoes makes a significant contribution to keeping feet cool and dry even in hot temperatures. Even on particularly warm days, the ventilation ensures a comfortable fit and effectively prevents excessive sweating. However, the shoe is hardly suitable for lower temperatures, as the material has virtually no insulating effect.
One disadvantage, however, is that the fabric on the inside is too rough for the shoe to be worn comfortably without socks. The fabric rubs unpleasantly, especially on the heel , if no socks are worn. By not wearing socks, the shoe could offer an even more comfortable temperature level in summer.
The slip resistance of the ROYAL trainers is also very good. The sole has an effective tread pattern that provides sufficient grip for everyday wear. Despite the smooth surface of the sole material, the shoe offers good grip on wet, smooth tiles.
For our test, we received the shoes in size 42 for men and size 38 for women, so the shoes fit our tester with shoe size 42 very well. Our tester usually wears a size 39, but the shoes are clearly too small for her and she is unable to put them on. Nebulus shoes are available in sizes 36 to 42 for women and 41 to 46 for men.
If the shoe fits, it offers enough room for the toes and is comfortable to wear. The flexible sole and thin fabric ensure that the shoe is comfortable and light. As the thin fabric hardly retains its shape, the shoe structure adapts directly to the individual shape of the foot. Overall, the summer sneakers are comfortable to wear, even during long walks or sporting activities.
In summary, our practical test shows that the ROYAL trainers from Nebulus are particularly suitable for hot summer days thanks to their good ventilation. Here, the shoes impress with their comfort and good support. For colder days, however, we recommend different footwear due to the lack of insulation.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good quality in the lower price segment90 points
Rating cut4.2 out of 5.0 (men) on Amazon60 points
Total75 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the men’s version an average rating of 4.2 stars. The durability of the shoes is criticised in particular. Many customers like the fact that the shoes are also suitable for particularly hot days thanks to the thin fabric. In our practical test, we were able to confirm that the shoes are indeed particularly suitable for high temperatures. We are also very satisfied with the quality and workmanship of the shoes. No damage occurred during our practical test.

Prices of up to €149.95 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €23.90. With a price of €49.99 on Amazon, Nebulus trainers are currently in the lower price segment. The price ratio is reasonable for the quality and scope of services you get.
