GUMP: Sell GUMP socks in your registration funnel
Offer GUMP technical socks to your participants directly in your registration form.

GUMP is an njuko partner that lets you offer technical running socks as an add-on (upsell) in the registration funnel.
This integration makes it easy to add a product offer to your edition, while creating a relevant experience for participants and an additional source of revenue for your organisation.
GUMP manages the stock and validates editions before activation, to guarantee consistent product availability.

How to add the GUMP option to a form
1. Who is GUMP?
GUMP is a French brand of technical running socks.
The brand is built on a simple observation:
The sock is probably the runner’s most underrated accessory, and yet one of the most important when it comes to comfort and blisters.
Its positioning revolves around a strong message:
“Te faire vivre debout” (keeping you on your feet)
In other words: supporting runners right to the end of their effort, whatever the distance.
GUMP adopts an approachable, community-minded tone that is deeply rooted in running culture.
1.1 What makes GUMP socks different
Rather than multiplying product lines, GUMP has chosen a simple approach:
one universal, high-end technical sock, suited to:
-
road running
-
trail running
-
and even everyday use.
Its main technical features include:
-
Flat seams that limit rubbing
-
Reinforced zones at the impact points (heel, arch, toes)
-
Targeted compression that supports blood circulation
-
Technical fabrics that wick moisture better and help prevent blisters

3. Install the GUMP module
The GUMP integration is available as a partner module in the Store.
To install it:
Go to:
Store → search for “GUMP” → Install
Once installed, the module is available in your edition.
⚠️ Important
The edition must be validated by the GUMP partner before the integration can be used in your forms.
4. Configure the GUMP integration
Once the module is installed and your edition validated:
Go to:
Tools → GUMP
This step consists of mapping the participant fields that will be sent to GUMP.
4.1 Map the required fields
Map the following fields:
GUMP field | Recommended njuko field |
Last name | Last name field |
First name | First name field |
Address | Text field |
Postcode | Text field |
City | Text field |
Country | Country field |
Email field | |
Phone | Phone field |
This information is needed for the integration to work properly.
⚠️ Important
The fields must exist in your form before you do the mapping.
5. Add GUMP to a form
Once the mapping is complete, you can add the GUMP offer to the form of your choice.
Go to:
Configuration → Forms
Then:
-
Open the form concerned
-
Click Add a field
-
Search for:
GUMP
-
Select the GUMP field and add it to the form
6. Important points to know
A few things to keep in mind:
-
GUMP works as a simple additional option in the form
-
Organisers do not configure sizes or colours
-
Stock is managed by the partner
-
The edition must be validated by GUMP beforehand
This keeps the integration simple on the organiser’s side.
