Shoe Nails and Tacks

Shoe nails and tacks are some of the most traditional yet essential components in the footwear trade. They provide the mechanical strength needed to securely attach soles, heels, insoles and lifts, ensuring long-lasting and reliable repairs.

At Algeos, our range includes IVI nails, lasting tacks and clinching nails, each designed to meet the specific demands of shoemakers (everyday and orthopaedic) and repair professionals. Whether you are fixing lightweight fashion shoes, securing heavy-duty work boots, or performing precision insole work, our selection offers the right nail or tack for the job.

Selecting the Right Shoe Nails and Tacks

Shoe nails and tacks may be tiny, but they do the heavy lifting in footwear manufacture and repair. Pick the right fastener and your soles, heels and insoles stay secure, comfortable and durable. Pick the wrong one and you’ll fight splits, loose lifts and premature failures. 

This guide explains the main types, where to use them, and includes an IVI nails size reference you can rely on in the workshop.

What Are Shoe Nails and Tacks?

Shoe nails and tacks are hardened steel fasteners used to mechanically fix components such as insoles, soles, heels and heel lifts. Unlike adhesives (chemical bond) or stitching (textile bond), nails and tacks provide an immediate mechanical grip that’s ideal for high-stress areas, thick stacks and time-critical repairs. 

Modern shops often use a hybrid method - nails plus adhesive - for maximum strength.

Types of Shoe Nails and Tacks

  • IVI Nails: Fine, hardened steel nails for insole - for sole and heel work. Sharp points minimise splitting in leather, fibreboard and composites.
  • Lasting Tacks: Short, stout tacks used during lasting to secure uppers to the insole - temporarily or permanently depending on method.
  • Clinching Nails: Designed to bend and “clinch” back into the material, giving superb hold in heavy footwear and stacked heels.
  • Cobbler’s Tacks: Versatile, general-purpose tacks widely used in repair for soles, heels and accessories.

How to Choose the Right Fastener (Step-by-Step)

  1. Match to the job: Insole holding and thin soles - shorter, finer nails or tacks. Heels and thick stacks - longer nails or clinching nails.
  2. Assess the material: Delicate leathers and fibreboard prefer fine, sharp points. Dense rubber and stacked leather tolerate longer gauges.
  3. Decide permanence: Lasting tacks suit temporary positions; IVI/clinching nails are best for permanent strength.
  4. Size correctly: Use the IVI reference chart below to pick a sensible length for insoles, soles or heels.
  5. Combine for durability: For high-wear areas, use nails with a quality footwear adhesive for belt-and-braces reliability.

IVI Nails Reference Chart

Common IVI nail sizes with typical applications and quick selection notes.

Nail Size (mm) Typical Application Notes
10 mm Light insole fixing; small children’s shoes Fine, sharp point helps prevent splitting
13 mm Thin soles; holding insoles in place Often paired with adhesive for extra hold
16 mm General sole attachment; small heel lifts Popular all-rounder in repair shops
19 mm Heels on women’s shoes; medium lifts Good strength without excess bulk
22 mm Men’s heel lifts; thicker soles Strong mechanical grip for heavier footwear
25 mm Heavy-duty heel nailing; work boots; stacked heels For maximum strength where it’s needed most

Comparison: Nails vs Tacks (At a Glance)

Type Best For Main Advantage Watch-outs
IVI Nails Soles, heels, insoles Precise, strong hold; minimal splitting Pick the right length to avoid breakthrough
Lasting Tacks Uppers to insole during lasting Fast placement; good temporary fixation Not a substitute for final permanent fixing
Clinching Nails Heavy footwear; stacked heels Exceptional grip when clinched Requires correct anvil/technique to clinch cleanly
Cobbler’s Tacks General repairs; accessories Versatile; easy to drive Shorter length limits deep fixation

Workshop Tips for Best Results

  • Pre-drill cautiously in very hard stacks to guide longer nails and avoid drift.
  • Angle matters: Slightly toe nails toward the denser substrate for better bite.
  • Use the right last/anvil to support material and prevent surface bruising.
  • Finish properly: Dress heel seats and outsoles after nailing to remove proud points.
  • Quality check: Flex test and heel-pull test before handing back to the customer.

FAQs

Are nails still necessary if I use premium adhesive?
Yes. Adhesive provides excellent bonding, but nails deliver immediate mechanical strength—especially useful in heels and thick stacks.

Which IVI size should I use for a standard men’s heel lift?
Start with 22 mm and move to 25 mm for thicker or heavily loaded boots.

Will nails split leather?
Use fine, sharp IVI nails (10–16 mm) and correct technique; splitting is uncommon when sized appropriately.

Can I clinch any nail?
No. Use clinching nails designed to bend and lock; support with the right anvil to avoid marks.

Do I need different nails for fibreboard vs leather?
Fibreboard and dense rubbers often tolerate slightly longer nails; always test on offcuts and avoid breakthrough.

Choosing the right shoe nails and tacks is about matching length, type and technique to the job. Keep the IVI chart handy, combine nails with quality adhesives where appropriate, and use proper support and finishing. The result: stronger, cleaner, longer-lasting repairs and builds.
