Double S Flat Straight Bar by Mustad

The Mustad DOUBLE S Flat Straight Bar is a bar-shoe designed to provide heel support and distribute load across the hoof through its straight bar design. It is available in the smaller section sizes (000 through 2), which makes it appropriate for lighter or sport-horse applications. According to a supplier listing, the size options for this shoe include 000, 00, 0, 1 and 2.
As a straight-bar rather than an egg-bar or heart-bar, it offers a stable structure without a deep heel branch, making it useful for horses needing bar shoe support but not extreme heel load redistribution.

Usage

• Target Species: Horses (sport or therapeutic use)

• Application: Fitted by a competent farrier during shoeing when a straight bar shoe is indicated (e.g., for extra heel support, stability or in remedial hoof/leg scenarios).

• Method:

  1. The farrier selects the correct size from 000 → 2 for the horse’s hoof and work requirement.

  2. Prepare the hoof: trim, clean, and ensure correct hoof balance and sole clearance.

  3. Fit the Straight Bar shoe: place on hoof, ensure full contact of the bar across the quarters/heels, nail or clip as required, correct clinches and check fit.

  4. After shoeing, monitor the horse’s movement, hoof health and fit of the shoe; check at each reset whether the shoe remains well-fitted.

• Frequency:

  • Use each shoeing cycle when a straight-bar style is appropriate for that horse.

  • Inspect at each shoe-change: if the bar section is worn, misaligned or interfering with the hoof sole/branch clearance, replace or adjust.

Features and Benefits

• Straight bar design: Provides heel branch support without the more aggressive shape of an egg or heart bar, suitable when moderate heel support is needed.

• Sizes 000 to 2: Allows fitting for smaller or sport-horse-sized hooves with refined section increments.

• Brand backing (MUSTAD): A reliable farrier brand with consistent patterns, allowing better fit and modification.

• Therapeutic/Support options included: Some listings include clipped side variants or quarter clip versions, offering flexibility in fit and retention.
