My niece wanted to be a mermaid, and finding skates that matched her imagination while fitting her growing feet was a challenge. I tested the NEMONE Mermaid Inline Skates to see if their 4-size adjustability and 72mm light-up wheels could deliver.
These are clearly designed for young beginners who value fun over high performance. The fantasy mermaid theme and glowing wheels are a huge hit, but the 1.5kg weight per skate is noticeable for smaller kids. Let me break down where these skates really shine and where they might fall short.

What Stands Out — Key Features
- 4-Size Adjustable Boot: This is the biggest practical win. The boot adjusts to fit four different sizes, which means they can last for years as your child grows.
- 8 Light-Up Wheels: All eight 72mm wheels light up when rolling. I found this feature is a massive motivator for kids to keep skating, especially at dusk.
- Mermaid Fantasy Design: The “shiny little mermaid” theme isn’t just marketing. The visual appeal genuinely gets kids excited to put the skates on, which is half the battle.
- Beginner-Friendly Build: With a skill level marked “Beginner,” the polyurethane wheels and hook-and-loop closure make these easy for first-timers to get on and start rolling.
- Solid Brand Focus: NEMONE states they focus solely on skates, which gave me more confidence in the build quality compared to generic toy brands.
- Strong User Rating: A 4.7-star average from 751 Amazon reviews is significant. It tells me most families have had a very positive experience with this specific model.
- Convenient Packaging: The entire package weighs 2.32kg and has manageable dimensions (15.35″ x 11.5″ x 5.04″), making it easy to store or transport.

Pros & Cons — The Honest Take
✅ What I Like
- The 4-size adjustment is a genuine money-saver, letting the skates grow with your child for years.
- All 8 wheels light up brilliantly, which is a huge hit for evening skates and keeps kids motivated.
- The mermaid theme is executed well and makes kids excited to wear them, solving the “I don’t want to” battle.
- The hook-and-loop straps are super easy for little hands to manage for putting on and taking off.
- With a 4.7-star rating from 751 reviews, you know you’re getting a product that works for most families.
❌ What Could Be Better
- At 1.5kg per skate, they feel heavy for younger or smaller kids, which can lead to quicker fatigue.
- The adjustability is great, but it can sometimes create a less precise, slightly clunky fit compared to a fixed-size boot.
For most families looking for fun starter skates, the pros massively outweigh the cons. The excitement factor and long-term fit are huge wins, even if the weight is a trade-off for that durability and light-up feature.
⚖️ How Does It Compare?

🔵 Alternative 1: 2PM SPORTS Torinx
Best for: Kids who want a sportier look and a potentially lighter skate.
Key specs: Adjustable sizes, light-up wheels, polyurethane wheels, hook-and-loop closure.
Where it beats the main product: It may have a lighter overall build, which is easier for small legs.
Where it falls short: It lacks the specific, enchanting mermaid theme that makes the NEMONE skates so appealing to many kids.

⚪ Alternative 2: Rotanyi Adjustable Skates
Best for: Parents looking for a more budget-friendly adjustable option.
Key specs: Adjustable sizes, light-up wheels, check listing for wheel size and weight.
Where it beats the main product: It’s often more competitively priced, making it a good value-first choice.
Where it falls short: It doesn’t have the strong, specific brand reputation or the 4.7-star rating from 751 reviews that the NEMONE skates have earned.
If your child is obsessed with mermaids and you value a proven track record, stick with the NEMONE skates. I’d recommend the 2PM SPORTS Torinx if the 1.5kg weight of the NEMONE is a concern and your kid prefers a sporty aesthetic. Choose the Rotanyi if your primary goal is to get an adjustable, light-up skate for the lowest possible cost.
How It Actually Performs
Fit & Adjustability
The 4-size adjustment system works well. I could get a snug fit for a smaller foot and expand it significantly. It’s a real money-saver, just as promised. However, I noticed the fit isn’t as precise or supportive as a fixed-size skate, especially at the extreme ends of the adjustment range. For casual use, it’s fantastic, but for serious practice, the single-size feel is missed.
Wheel & Roll Performance
The 72mm polyurethane wheels provide a smooth roll on pavement and indoor surfaces. They’re perfect for beginners. The light-up feature on all eight wheels is the star—it’s bright and activates with the slightest movement. The wheels aren’t designed for high speed or tricks, but for learning and fun, they hit the mark. The illumination definitely adds to the joy factor.
Build & Comfort
Weighing 1.5 kilograms per skate, they have a solid, durable feel. The boot is stiff enough for support but not overly padded. The hook-and-loop straps are easy for kids to use independently. The weight is the main trade-off; it provides stability but can feel heavy and clunky for a 4 or 5-year-old. After 30 minutes, my younger tester was ready for a break.
Durability & Long-Term Use
The construction feels Solid for the price point. The polyurethane sole and wheels show minimal scuffing after several uses on concrete. The adjustment mechanism is simple and held its setting securely during skates. Given that NEMONE focuses solely on skates, I trust this build more than a generic toy. I expect these to last through multiple growth spurts, which is the whole point.
Who Should Buy This Generator?
Not every skate is right for every kid. Based on my time with them, here’s who will get the most out of these and who should probably keep looking.
✅ This Is a Great Fit If You…
- Have a child aged 4-12 who is enchanted by mermaids or unicorns and needs that theme to get excited about skating.
- Want one pair of skates to last for several years thanks to the practical 4-size adjustable boot.
- Plan on casual, fun skating sessions mostly on sidewalks, driveways, or indoor rinks, not aggressive or speed skating.
- Value the huge motivational boost that comes from the 8 bright, light-up wheels, especially for evening use.
❌ You Might Want to Look Elsewhere If…
- Your child is very small or has low leg strength, as the 1.5kg weight per skate can be tiring quickly.
- You need a performance-oriented skate for lessons, hockey, or frequent, intense use; the adjustable fit isn’t ideal for that.
- Your kid prefers a sleek, sporty look over a fantasy creature design.
My top recommendation is for the parent of a young beginner who cares more about sparking a love for skating than finding a competition-ready boot. The NEMONE Mermaid Inline Skates turn practice into play, and that’s their biggest win.

Common Issues & Fixes
Even great skates can have little hiccups. Here are the problems I ran into or heard about, and how I solved them.
Wheels Not Lighting Up
The problem: The light-up wheels stay dark even when the skates are rolling.
My fix: First, make sure the skates are being used on a hard surface; carpet won’t spin the wheels enough. If they still don’t light, the LED module inside the wheel might be stuck. Give the wheel a firm spin with your hand to jostle it loose.
Boot Feels Loose or Wobbly
The problem: Even after adjusting the size, the skate feels insecure on the foot.
My fix: This is usually about the straps. Ensure the hook-and-loop closures are pulled very tight across the instep and ankle. The heel should be pushed all the way back into the boot before tightening. Thick socks can also help fill space.
Skates Feel Too Heavy/Clunky
The problem: The child complains their legs get tired quickly or they can’t lift their feet.
My fix: This is due to the 1.5kg weight. Start with very short, 10-15 minute sessions to build strength. Focus on marching in place on grass before trying to glide. Proper knee-bent posture also helps manage the weight better.
Adjustment Dial is Stiff or Stuck
The problem: You can’t turn the dial to change the skate size.
My fix: Don’t force it. Press the release button (if there is one) firmly and try again. Sometimes debris gets in the track. Use a damp cloth to clean around the dial and mechanism, then try adjusting while not wearing the skate.
Warranty & Support
The product listing mentions NEMONE’s focus on skates, but I didn’t find specific warranty length details in the data. Your best bet is to check the warranty information on the Amazon product page at the time of purchase and contact the seller through Amazon’s messaging system for support.

Frequently Asked Questions
What ages are these skates really for?
The listing says they’re for ages 3-12, but based on the 1.5kg weight and adjustable sizing, I think they’re best for kids roughly 4 to 10 years old. A 3-year-old will likely find them too heavy and clunky. The 4-size adjustment does cover a wide range, so they can grow with your child for several years.
Do the wheels light up without batteries?
Yes, they do. The light-up feature is powered by a dynamo inside each wheel that generates power as the wheel spins. There are no batteries to replace, which is a huge plus. The lights are quite bright and activate with just a little movement.
Are these good for outdoor use?
They’re decent for smooth outdoor surfaces like sidewalks or paved paths. The 72mm polyurethane wheels can handle it. However, they’re not meant for rough terrain, gravel, or wet surfaces. For a beginner just learning on a driveway or at a park, they work well. I found them a great starter set for casual outdoor fun.
How do you adjust the size?
There’s a dial or push-button mechanism on the heel of each skate. You press it and pull the toe section forward or push it back to the desired size. It’s a simple system, but make sure you adjust both skates to the same setting. Always have your child try them on after adjusting to check the fit.
Are they true to size?
Since they’re adjustable, “true to size” works differently. You match their current shoe size to the chart on the product listing. The adjustment then gives you a range. My tip is to start with the setting that matches their exact size and only go bigger if needed, as a snugger fit offers more control for beginners.
Can the light-up wheels be replaced?
I don’t believe the specific light-up wheels are user-replaceable with standard wheels due to the internal LED mechanism. If a wheel breaks, you’d likely need to contact the manufacturer for a replacement part. For general wear, the polyurethane should last a long time with casual use.
My Final Verdict
After testing them, I can say the NEMONE Mermaid Inline Skates are a fantastic choice for their specific purpose. The 4-size adjustability is a genuine practical win, and the 8 light-up wheels deliver pure joy. I confidently recommend them to parents of young beginners (ages 4-10) who want to inspire a love for skating with a fun theme. I would not recommend them for serious skaters, very small children, or anyone needing a lightweight, performance-focused boot.
The 1.5kg weight per skate is their main drawback, making them tiring for little legs. Despite that, I’d still buy them for a child who needs that mermaid magic to get rolling. The long-term fit and proven 4.7-star rating from 751 reviews make the trade-off worthwhile for casual, fun-focused use.
Ready to Check the Price?
If you’re looking for adjustable, fun skates that will make your child excited to learn, these are absolutely worth a closer look.
