Hi @hayclowz ,

This is Victor from PageFly - Landing page builder, I’d like to suggest this idea:
Step 1: Go to Online Store->Theme->Edit code
Step 2: Asset->/section-main-product.css->paste below code at the bottom of the file:

.product-form__input input[type=radio]+label {
   font-weight: bold;
}

Hope my answer will help you.

Best regards,

Victor | PageFly

Hey, @hayclowz

Since you are using a Shopify-developed theme, and assuming you are on a paid plan, this may be an eligible design customization request you can make to our themes team. As a part of your 60 minutes of complimentary design time.

Please visit our help center and log in to your account to create a support request with a support advisor. From there, our themes team will look into your request for eligibility.

If there is anything else I can help you with, please let me know.
