Mobile optimized - consistent experience across all devices

Kalles is 100% responsive to make your website look beautiful in all devices and resolutions. The theme is mobile ready and has been fine tuned to look great on any device.

Speed loading less than 3 seconds

You have to exchange in speed and features, with themes from the Shopify theme store, they're fast, but you don't have many features and you have to pay a lot of money for a third-party app, which makes your store slower. With some Shopify themes in ThemeForest, you have more features but the speed is terrible, but with Kalles - You have both, how amazing it is.

Product video thumbnail and 3D

Now you can upload a 3D model or video directly to your product pages as easily as an image—without the need for custom code or a third-party app. Today, video plays a pivotal role as a marketing asset on social media, in crowdfunding campaigns, your homepage, and more. But on product pages, they can help create demand for your products right at the point of purchase.

Use any Google Font and Shopify Font

Do you know? Using an accurate font will help your store look more professional and up to 30% different before changing a font. In design, fonts are the most important thing and it determines whether or not the design is good. With Kalles, you can use any Google font or Shopify font. If you want to use Custom fonts, we strongly recommend Fontify, we also have font installation service.

What Customers Say About Us

In the 8 months since the initial release, we have received a lot of praise from our customers. Let's see what customers have to say about the quality and service from The4.

I've also used Ella, Wokiee but Kalles is what I recommend. They have great support. Special thanks to Sarah for her prompt and detailed support. I have many questions and custom requirements for editing the theme but Sarah never let me down and never became impatient like support from other themes.


Excellent well wrote code! It was easy for me to customize the theme, including deep dives in the Templates and Sections. I had my new design up fast, and everything functioned perfectly.


This theme is really easy to work with, the help documents are adequate and the support is great. Having zero programming background makes setting up Shopify store with Kalles Theme so much easier.


Wanted to choose every selection of this question but gives me chance to chose only one! This team ''The4'' is really best one! Dont try other authors. After many other themes that I have used finaly I get this one and I can defently say that this theme is the best one, very clean, lightweight and fast. With tons of customization options and much more. Plus dont forget about support! Thank you very much The4 team.


Kalles is a great theme, it comes with a lot of good plugins, and it helps me save a lot of money on plugins. I used it in 2 stores and I recommend everyone try it.


This is the best Shopify theme I've ever bought. Super clean design, extreme customizability (great for both general and niche stores), and, so far, no bugs! (which pleasantly surprised me) The theme can be edited without much fuss. I barely need to consult any tutorial and documentation to get my way around the settings. The editing menus (settings) are well defined and easy to understand. The customer support is also on point! Fast to respond and very helpful. Overall 5/5 stars!
