CHAYA Emerald Hard

CHAYA is a pure roller derby and rollerskate brand from POWERSLIDE. They have been working for over three years to perfect their product line and to make sure they introduce a unique design which does not compare with any other brand on the market.
CHAYA's image is clean, pure, and only focused on what is needed for boots and plates. Fully functional product with great design and style combining function and fashion.

The Emerald offers a breathable boot with added comfort and a super smooth skating feeling. The extra smooth, feather light Power Knit textile upper wraps your foot like a second skin. The Emerald re-defines comfort and its look and specialized materials set new standards. This sporty, sophisticated skate is a slender fit and has the added advantage of being super light-weight.


The Chaya Emerald low cut boot is very light-weight and comfortable. The sporty look is emphasized by the Power Knit upper, a high tech knitted textile, which is characterized by its durability and low weight. Furthermore it can be laced perfectly and wraps your foot like a second skin. The toe area is protected by a layer of PU-leather material. The hard composite outsole provides a good power transfer.


The plate is made of a fibreglass reinforced nylon composite material, which makes the plate extra stiff and responsive and provides a smooth ride. The king pin and axles are made of steel while the cushions are made of high quality PU for easy turns and skating pleasure.

This plate features the Power Toe System (PTS) for better performance, more power, speed and control. The front of the plate is raised and angled closer to the natural bend of the out sole. This ensures that the muscles of the feet are pre-tensioned, which makes it easier to push the skates.

The replaceable toe stopper is placed off set towards the inside of the plate to follow the anatomical and natural movement when a skater wants to stop or is walking on the toe stopper. The stopper itself is made of long lasting natural rubber material, which provides great performance.


The “Octo Edge” wheels of the Chaya roller skates are made of SHR PU-material. With a classic roller derby size of 59mm x 38mm and a hardness of 92A the wheels provide a great rolling performance with the right amount of slide to perfect your stops. They are perfect for your inoor rolling activities. 


WICKED (WCD) is a new high end bearing brand specialized for all kinds of rollsport. WCD is made of the best available raw materials and crafted with high quality to guarantee a fast and smooth ride but also long lifetime. WCD ABEC 7 Freespin bearings have a very good and smooth freespin. The bearing contains 7 chrome steel bearings and a light weight but resistant nylon cage. One side is covered by a non contact rubber coated RZ shield. A synthetic oil from Japan is used for this high end bearing.

Sizing information - Find the correct skate size

For beginners of our sport it's not quite easy to decide which size will fit for your feet. Here we will show how to choose the correct size based on your real foot length.

First of all you should measure your feet:

Therefore put on some socks you would also wear while skating. Then press your heel against the a wall (as shown on the picure below) and take the length to your longest toe. Note the length in millimeter.

When you have chosen a roller skate and opened the product page you'll find a sizing chart on the right hand side and below the product picture under "availability/prices".

Example! This is how the sizing chart can look like:

There you can see the "length" in millimeter. This length refers to your measured foot length. Please don't pay attention on the EU, US or UK sizes. Due to different fits of shoes and roller skates it's quite difficult to choose the correct size with these information.

IMPORTANT: The exact fit of the roller skates also depends on your individual foot structure.

So if you have a normal foot structure, neither very narrow nor very wide, you can go for the exact measured foot length.

But if you have a very wide foot structure you should take one size bigger.

Example: Your measured foot length is exactly 251mm and your foot structure is normal, you should go for S 7.0 on the sizing chart shown above. Because if you are between two sizes you should go for the next bigger size. With very wide wide feet we recommend taking the next size what would be S 7.5 in this case.

These recommendations are made to find the tight but comfortable fit for your roller skates. Since roller skates are sport equipment the correct fit is very important. Please note that due to the huge amount of different foot structures and skate types there will be no guarantee for the perfect fit. But our recommendations refer to our experiences and the experiences of our customers.

If you still have questions or feel unsafe deciding what the correct size should be don't hesitate to contact us: info@rollerderbyhouse.eu
