Buying guide for fitness inline skates

When looking for fitness inline skates there are 3 things you need to have in mind: You should choose about one European or a half UK size bigger than your normal shoes, consider the wheel size and consider whether you want a soft-boot or hard-boot.

See this video where we quickly guide you through the most important things you need to know before your first purchase.

Fitness inline skates are equally suitable for both workout purposes and nice and easy rides. They are well-known for their good fit and high comfort, and furthermore, they are breathable and feel good on the feet so you can skate with ease. Fitness inline skates can be used by people of all ages - kids as well as elderly people.

Fitness inline skates - for the healthy and social

Fitness inline skates are a fun way of burning calories while getting fresh air down your lungs. And on top of that it is a great social activity to be doing with family, friends or your partner.

A lot of doctors even recommend inline skating as an alternative to running if you have problems with your knees, because when you skate, you make long, sliding movements that are more gentle on the knees compared to the impacts you experience when running. And you still get the pleasure of a nice time out in nature.

Recreational inline skates exist in many different models and designs, making it possible for you to find a pair that you like.

Wheels for fitness inline skates

Wheel size

Choosing wheel size depends on the distance you would like to run.

  • For longer distances (e.g. a marathon or normal workouts) you should use bigger wheels. This will make it easier for you to maintain the speed and you use less energy. We recommend a wheel size of 90-100mm in diameter or even 110mm.
  • For shorter distances (e.g. city skating) you should use smaller wheels. This will make your skates more manoeuvrable, making it easier for you to stop and turn. We recommend a wheel size of 80-84mm.

Wheel durometer

The wheel durometer is indicated with an A. For fitness skates the suitable durometer is 78-85A.

  • The higher the A number is, the harder the wheels are.
  • The lower the A number is, the softer the wheels are.

The wheel durometer affects the lifespan, grip, speed and shock absorbing effect of the wheels.

  • Softer wheels equal better grip and shock absorption, but shorter lifespan and less speed.
  • Harder wheels equal longer lifespan and higher speed, but less grip and shock absorption.

Read our guide “Wheel terms explained”, if you wish to learn more about skate wheels.


To ensure that your inline skates perform their best, it is important that you treat the bearings well. This means:

  • Avoid water and moist as much as possible.
  • Avoid sand and dirt.

The bearing is a component inside the wheel important for the wheel’s ability to turn. At SkatePro we typically specify the bearings according to the ABEC scale which defines the precision of the bearing.

  • The higher the ABEC rating, the higher precision and less roll resistance you get - this makes it easier for you to maintain speed and thus getting a better roll.

We recommend that you buy from a recognised brand instead of solely focusing on the ABEC rating since the quality of a bearing is not determined by ABEC itself, but several parametres combined. This means that an ABEC 5 bearing from one brand can actually have a better roll than an ABEC 7 bearing from another brand. If you wish to get into more details with bearings, you can read our guide “Buying bearings”.

Boots and liners

Soft-boot vs. hard-boot

Whether you choose a soft or hard-boot/shell depends on your taste.

  • A soft-boot/shell is typically more comfortable and well-ventilated.
  • A hard-boot/shell is typically more stable and provides more control.


For some recreational inline skates you can buy a separate liner (inner boot) to make the boot more comfortable. However, with fitness skates this is typically not necessary since they are already designed with a comfortable liner from the beginning providing high comfort - something they are already well-known for.

Women’s and Men’s inline skates

Inline skates are often separated in women’s and men’s models, but usually there is no other difference except that of the visual design. Some brands, however, have designed models that aim specifically at women’s and men’s feet.

  • Always read the size guide offered to you on the specific product pages if available.
  • Choose approx. one EU size bigger than your normal shoe size unless indicated otherwise in the size guide.
  • Try the skates on for approx. 10-15 minutes. Only test them indoor in case you want to return them.

You should be able to move your toes a bit. They should not touch the nose of the skate. If your rollerblades squeeze already from the beginning, they will hurt the moment you go for a longer run. However, remember that boots tend to expand a bit after some time, and if you have a soft-boot it will expand more than a hard-boot.

People with slim feet frequently tend to choose certain models such as the K2 skates since they feel tighter around the foot. On the other hand, brands like Rollerblade and Powerslide are frequently preferred by people with wider feet.

Since the fit of a skate is a personal matter and no feet are alike, you can never be 100% certain that the first inline skates you try on fit perfectly. That is wahy you have to try your way through - just like with regular shoes. Also remember to use the specified size guides - they will help you a long way.

Closure System - Buckles and Laces

Fitness inline skates are often equipped with a closure system consisting of both buckles and laces. Some models even have a special wire tightening system where the skates are tightened as you turn the knob. Buckles are faster than laces and it is easier to get the same fit again. With laces, however, you can tighten the boot differently along the foot.

Whether you choose one or the other of the closure systems is a question of personal preference. Most importantly you should choose a pair of skates with a closure system that provides you with the right fit in order for you to gain full and optimum control over your rollerblades.


Most rollerblades come with a brake pre-mounted. You can switch it to the other skate if you prefer to brake with the other foot. Since brakes are a wearing part and will wear down at one point, we recommend that you buy an extra pair from the beginning.

This way you always have a pair ready to use and you also avoid the risk of a brake having expired. Recognised brands, however, usually offer brakes for the same model for a long time.


The frame of fitness inline skates often consist of an aluminium frame which is more stiff and stable thus providing better power transfer compared to a nylon/composite frame. If it is important for you to cut off seconds of your lap time, you should go for an aluminium frame. But if you are only planning to use your rollerblades for workout purposes and cosy rides, it does not matter which you choose.

Skate Protection

We always recommend that you use certified safety equipment. That is why you only find equipment that has been certified according to the EN 1078 norms. Moreover, most of our gear has been tested further by skaters.

As a minimum we recommend a skate helmet since it provides extra protection to the back of the head, and wrist guards since you usually use the hands during a fall.

Remember that skate protection does not only protect you but it can also give you a sense of safety giving you more courage to try more things and thus learn faster. And if you were to fall, it would not hurt near as much as if you fell without your safety gear on.
