Flex-On "Balance" Composite stirrups


The lower-cost composite-based version of Flex-on's innovative hi-tech stirrups, designed - and scientifically proven - to provide help with riding position and reduce strain on the leg muscles and joints. These offer the same amazing ride as the original aluminium-framed model and have to be tried to be believed.. (see note below re. our tester service)

Stocked in black, grey and brown but also available to order with custom coloured frames and/or elastomers! (see product photos for stocked colour combinations, plus "customisation options" below for other options ). See also "More about Flex-on Stirrups" for more information on customisation options and an explanation of the differences between the Composite, Pro (Alu frame) and Safe-on models. 

Why we chose them:

  • Lightweight: strong but lightweight frame (450g) uses hi-tech design and polyamide composites with steel core
  • Innovative balance: clever offset and skewed stirrup-leather slot, plus carefully designed multi-inclination footbed, help create the ideal position for rider's leg and foot
  • Shock absorbing: Elastomer shock absorbers supporting the footbed plus flexibility built into the frame help absorb shocks and vibration 
  • Ultra-grip mixed inclination footbed: small studs embedded in the stirrup tread grip the boot to ensure excellent stability of ride and connection with the horse, without damaging boots. 
  • Colour options: can be ordered in a variety of colour combinations - e.g. to match your riding colours (see below)



Flex-on have informed us that they are discontinuing the mixed footbed type that we have generally recommended for UK riders, and we can now no longer order this footbed type from Flex-on. We still have stock of Composite stirrups in black, grey and brown and Alu stirrups in Sidereal Grey with mixed ultra-grip footbeds, but we regret we can now only supply custom stirrups with inclined or flat footbeds.  We have ordered a stirrups with flat footbed to offer as testers and will be very interested in feedback on these.  


We are Flex-on's original UK retailer, launching them at Olympia in 2014. We have unrivalled experience with these excellent products.  We strongly encourage you to consult us when choosing between these and Flex-on's other stirrup models, as well as when choosing customisation options such as footbed types - our aim is to ensure you get the right product and configuration for your needs. We also offer our tester service which also allows you to try out different models and/or footbed types before committing. 

"Having tried them myself, it's clear the designers have developed a stirrup that makes riding more comfortable and gives you a helping hand with your riding position - both pretty valuable results"
Alison Lowther, Tried & Tested review in Your Horse Magazine, April 2015 (see product images for full article)

Customisation options
Flex-on offer a wide range of customisation options:

  • Frame/elastomer colours: These stirrups are available in several frame colours; in addition the rubber elastomers under the footbed can be ordered in a variety of colours to provide a colourful accent (for available colours & examples, see product images). We hold in stock for immediate delivery dark grey, matt black and brown frames (all pictured), each with matching elastomers. Any other colour combination can be requested as a special order - lead-time is usually 1-3 weeks. To order, choose the "Custom" colour option and specify your required frame and elastomer colours in the box provided for special order details on the basket page when checking out.
  • Custom inserts: Our stock grey, black and brown stirrups and any custom order stirrups are supplied with Flex-on's standard black inserts, with the "-on" element of the logo coloured to link to the elastomer colour. As an alternative to these standard inserts, custom decorative inserts can be ordered as an additional item (see "related products" below), and are easy to swap over. 
  • Footbed options: We supply these stirrups as standard with the "mixed inclination" footbed and ultra-grip studs. If desired we can replace the standard footbed with one without the ultra-grip studs (we recommend this for children and adults under 120lb), or with the alternative "inclined" footbeds, with or without studs - just choose the "custom' option and indicate your footbed preference in the "Special order details" box at checkout.  We can also special order the stirrups with Flex-on's fully inclined or flat footbeds, but we caution that everyone who has tried them so far prefers the mixed inclination type, both for jumping or dressage.
  • Footbed surround colour : The footbeds described above are always black. Traditionally these have been set into a light grey composite platform on the Balance stirrups, but Flex-on now offer the option of specifying with a black or white surround.  Our standard stock Balance stirrups come with light grey surrounds. Unless otherwise specified custom orders will be supplied with light grey surrounds.    

Ordering custom options: Choose the "custom" option for any special order requirements - ie any frame and/or elastomer colours other than our standard black, dark grey or brown frame with matching elastomers, or any footbed type other than our standard mixed ultra-grip type. Please specify your special requirements in the box provided for special order details at checkout.

If wanting non-standard decorative inserts, please order the separate custom insert product as an additional item and specify the insert style wanted in the special order details box. 


Footbed size: 4 ¾"

Fitting note
Due to their special asymmetric design, these stirrups come with distinct left and right sides, marked "R" and "L" on the frame

Tester service
In common with many other products we sell, Shadow Horse offers an opportunity to "try before you buy" with tester stirrups that can be ordered to try out for a week or two.  See the "Flex-on testers" product in the Flex-on brand collection
