How to use ENGO Blister Prevention Patches:
Tips & Techniques and FAQs

ENGO® Blister Prevention Patches allow athletes to lower friction forces in areas where hot spots and blisters commonly form; effectively preventing blisters altogether. Patches remain in place for extended period of time. Effectiveness does not depend on sock type, footwear or insole / footbed chosen. 

Select a patch based on coverage required:
A rule of thumb is to select a patch that is larger than troubled area or blister

• Large oval: heel, arch, ball of foot, side of foot 
• Small oval: toes, heel 

Peel white backing partially, forming a tab to hold while handling patch 
Apply adhesive side of blue ENGO patch to desired location of dry footwear 
Peel remaining backing away from patch 
Press firmly around entire patch surface to secure. 

ENGO’s adhesive is pressure-sensitive. Therefore, as pressure increases so does patch conformance & adherence. Patches will eventually need replacement. Replace ENGO when the blue top layer wears through, or completely releases from, the white support layer.

ENGO Removal Instructions
To remove worn patch, simply pull from edge and peel it off. Replace with a new patch. For easier removal, heat patch slightly with blow dryer before pulling away.

Tips & Techniques

1. For easier patch installation, remove ½ of the patch from the backing. Fold backing to create a tab. Use tab for handling patch. Once patch is in desired location, remove remaining backing. Press to secure. 
2. All ENGO patches can be custom-trimmed to desirable size & shape. We recommend rounding corners.
3. For easier removal of ENGO patches, use a blow dryer or heat gun. 
4. If blisters form at interface of footwear & insole, use two patches. One patch is placed on the footwear. The other patch is placed on the insole. A smooth, blue interface is created. 
5. ENGO will adhere best when applied to a dry surface. Apply patches prior to activities for best results. 
6. ENGO may last longer when anchored to a surface. For example, wrapping patches around the edge/sides of the insole. 
7. ENGO packaging was designed with your needs in mind. The re-closable, heavy-duty bag used to package ENGO protects patches from elements and preserves product quality. We recommend that you store unused patches in the bag. 
8. Some locations in footwear are hard to reach (i.e. toe box). To place ENGO in these locations, try this technique: remove ½ of the patch from the backing. Fold backing to create a tab. Place the patch in desired location. Press to secure. Remove the rest of the backing. Press to secure. Or, simply place the patch on your sock. 
9. Not all friction is bad. Friction is useful to help secure feet in shoes and equipment on bodies. Select a patch that is slightly larger than the targeted/troubled area, thus reducing friction only where needed.

Frequently Asked Questions (FAQs)

Q: How does ENGO prevent blisters from forming?
A: Blisters are caused by friction. Heat and the resulting perspiration increase friction and weaken the skin. By reducing, or eliminating, any one of these three components, blister formation can be prevented. ENGO reduces friction to levels that prevent blisters, despite the presence of heat and moisture.

Q: Does ENGO help if I already have a blister?
A: Yes. Apply ENGO to the respective area of your footwear. ENGO virtually eliminates rubbing between your footwear and your sensitive, damaged skin allowing IMMEDIATE RELIEF and FASTER HEALING TIME.
(NOTE: we recommend covering your blister with a traditional treatment method to provide protection from infection until your blister is healed)

Q: Can ENGO help my calluses?
A: Yes. Calluses are caused by the same repetitive skin loading that form blisters. The difference is that calluses develop at less intense levels of repetitive loading and require longer periods of time to form. By using ENGO to reduce friction, epidermal cell proliferation and callus thickness are reduced. Callus reduction may take one to three months due to the delay in our skins responsiveness. 

Q: How long will each patch last?
A: The average use is four weeks. It depends on your activity level & terrain. Users have gone 300+ miles on one patch. Compare that to one-time-use products. Replace patches when the blue top layer wears through, or completely releases from, the white support layer. 

Q: Can I apply ENGO to my skin?
A: ENGO was designed for equipment, socks, insoles and footwear, so we guarantee its effectiveness for those applications. ENGO has not been tested on skin, so we cannot guarantee how long it will adhere to skin. ENGO is latex-free in the event you choose to use patches in this manner. 

Q: Can I apply ENGO to socks?
A: The toe area of some footwear is so small that you may not be able to easily apply ENGO in this location. In that case, go ahead and put it on your socks. But note that while ENGO stands up to sweat, we can’t guarantee it will stand up to the 45 gallons of warm, soapy water used in the wash cycle.

Q: How do I remove ENGO?
A: Pull the patch from the edge and lift off. If you are not replacing the patch and adhesive remains, sprinkle talcum powder on the residue to eliminate tackiness. For easier removal of ENGO, use a blow dryer or heat gun. 

Q: How do I know which patch to use?
A: The rule of thumb is to select a patch that is ¼- ½ inch larger than the troubled area. Large ovals are useful for the heel, arch, ball of foot, side of foot. Small ovals are useful for toes, heels. Rectangles are useful for helmets, skates, boots. Remember, all patches may be trimmed to meet your location and contour needs.

Q: Does ENGO have an expiration date?
A: As long as you store your patches in the re-closable bag provided, ENGO will last several years. When patches are not protected, the adhesive shelf life may be limited to 24 months. 

Q: How thick is an ENGO patch?
A: 0.015 inch. Most credit cards are 0.032 inch thick. Thus, ENGO is about 1/2 as thick as your credit card. When ENGO is applied to footwear, volume is virtually unaltered.

Q: What happens to the performance of ENGO when my footwear gets wet?
A: ENGO’s performance is not adversely affected by sweat or low levels of moisture inside your footwear. Performance is affected when your footwear is soaked from the outside-in AND you continue participating in high intensity activity AND have not provided time for the footwear/patch to dry out. 

Q: What are some useful applications for ENGO patches?
A: Place ENGO wherever you experience blisters and soreness caused by the friction forces of repetitive rubbing.
