Zorqelun™ HeelLock Air Collar

Fine-Tune The Heel Fit Without Changing Your Shoe Size

Some shoes are not too big. They are simply too loose in one place. The length feels right. The front fits properly. The style looks perfect. But your heel still lifts slightly when you walk.

Traditional heel grips try to solve the problem with one fixed piece of foam. HeelLock Air Collar takes a completely different approach.

Using a discreet adjustable air-cushion system, it lets you fine-tune the space around the heel area until the shoe feels more secure and better fitted. Inflate for a closer fit. Release for more room. Adjust whenever you need.

Your Shoes Do Not Need More Padding.
They Need Better Space Control.

Most heel grips use fixed foam, creating one predetermined thickness. If it is too thin, the shoe still feels loose. If it is too thick, the shoe becomes too tight. HeelLock Air Collar gives you another option. Its compact air chamber can be adjusted gradually.

The Three-Part HeelLock Structure

01 — Central Air Chamber

The adjustable air chamber allows the internal volume of the collar to change. Inflate it for a closer fit. Release air to create more space.

02 — Contoured Heel Wings

The side sections follow the shape of the inner heel area. They help create a more continuous contact surface instead of relying on one narrow strip.

03 — Low-Profile Outer Layer

The outer surface is designed to remain discreet inside the shoe. Once installed, HeelLock Air Collar becomes part of the internal fit rather than looking like a bulky add-on.

Your Left And Right Shoe
Do Not Have To Match

Sometimes one shoe feels more secure than the other. HeelLock Air Collar allows you to adjust each side independently. You might need medium inflation on the right shoe and only light inflation on the left. You do not have to force both shoes into the same setting.

Use A Different Setting For Every Pair

• Leather Loafer: Light inflation.
• Structured Sneaker: Medium inflation.
• Dress Shoe: Minimal inflation.
• Boot: Higher adjustment depending on internal heel volume.

The exact setting is yours to control.

Made For Multiple Footwear Styles

HeelLock Air Collar is designed to work across many types of structured footwear while keeping the original shoe silhouette intact. The shoe stays the visual focus.

• Loafers: Reduce extra movement around the heel without changing the front fit.
• Dress Shoes: Fine-tune the rear fit while maintaining a clean silhouette.
• Sneakers: Add adjustable heel volume inside structured collars.
• Boots: Refine extra internal space around the heel area.
• Slip-On Shoes: Create a closer rear fit where traditional lacing adjustments are not available.

Better Than A Fixed Heel Grip

Traditional heel grips have one setting. HeelLock Air Collar has many. Traditional inserts come in predetermined thicknesses (like 2mm, 4mm, or 6mm). HeelLock can sit exactly between those settings.

• Traditional: Fixed thickness, foam-only structure, single fit setting, focused on padding.
• HeelLock Air Collar: Adjustable volume, air-adjustable structure, multiple fit settings, focused on heel-space management.

Need slightly more support? Add a little air. Too much? Release some. You decide the final fit.

How HeelLock Air Collar Works

The adjustment system is designed to be simple. You do not need an app, batteries, or tools. One small pump offers multiple settings.

• Step 1 — Position: Place inside the rear collar. Align center behind the heel with side wings following the internal shape.
• Step 2 — Secure: Fix the collar in place using the integrated attachment surface.
• Step 3 — Put On The Shoe: Wear the shoe normally before adding significant air for a baseline.
• Step 4 — Inflate Gradually: Add a small amount of air using the integrated control.
• Step 5 — Test The Fit: Walk briefly and check how the heel area feels.
• Step 6 — Fine-Tune: Add or release air until you reach your preferred fit.
