Garmin Forerunner 255 Strap: The complete guide to choosing well in 2026
Clipz-it
Published in July 2026 · Clipz-it Guide · Reading time: 9 minutes
The Forerunner 255 is probably Garmin's best mid-range GPS running watch, and it deserves a strap that lives up to its ambitions. Originally supplied with a standard silicone strap that ages poorly, it benefits from being equipped with a proper dedicated strap - for running, trail, or even the office if you want to wear it daily.
This guide provides you with the complete method for choosing wisely in 2026, avoiding compatibility pitfalls (the 255 uses 22mm while the 255S uses 20mm), and covering all real-world uses.

What you need to know about the Forerunner 255 and its attachment
The Garmin Forerunner 255 was released in June 2022. It uses a Quick Release 22mm attachment system - two standard spring bars that can be manipulated without tools.
This is a universal, non-proprietary system. Concretely, it means:
- You can change straps in 30 seconds without tools
- You have access to a huge catalog (any standard 22mm strap with spring bars works)
- You can switch from silicone to leather depending on your day
This is a real advantage over Fenix watches which use the proprietary QuickFit attachment - which is more rigid and offers fewer third-party options.
Critical difference: Forerunner 255 vs 255S vs 255 Music
Beware of this very common trap: the three variants of the Forerunner 255 do NOT all have the same attachment size.
| Model | Case size | Attachment | Our category |
|---|---|---|---|
| Forerunner 255 | 45.6 mm | Quick Release 22 mm | ✅ This article |
| Forerunner 255 Music | 45.6 mm | Quick Release 22 mm | ✅ This article |
| Forerunner 255S | 41 mm | Quick Release 18 mm ⚠️ | See 255S collection |
| Forerunner 255S Music | 41 mm | Quick Release 18 mm ⚠️ | See 255S collection |
If you have a 255S (the S = Small, smaller case), you should opt for 18mm, not 22mm. Make sure to check your model before purchasing.
The 5 common uses of a Forerunner 255 strap
Before choosing the material, first define your primary use:
- Pure running - 1 to 1.5-hour run, quality session, competition
- Trail and ultra-running - long nature outing, uneven terrain
- Triathlon - swim-bike-run sequence
- Active life + occasional running - you wear your 255 to the office and go for a run three times a week
- Stylish look, worn all day - you want your 255 to look less like a "sports watch"
Each use calls for a different material.
Reinforced sport silicone: the running standard
For: running, sessions, competitions, daily training
Silicone is THE material for running. Lightweight, firm on the wrist (wrist heart rate monitors need good skin-sensor contact), and rinses under the tap in 10 seconds. Perforated models are breathable and prevent moisture buildup after an intense session.
Avoid: cheap, overly soft silicones that lose their tension after 6 months.
Our sport silicones tested on Forerunner 255: from €14.99.
Braided nylon: my recommendation for versatility
For: trail, long outings, active outdoor life, discreet office wear
If I had to recommend just one strap for a Forerunner 255, it would be a breathable military braided nylon. Here's why:
- Featherlight (often < 20g compared to 30-35g for silicone)
- Dries quickly after rain or a spilled water bottle
- Understated textile look that works discreetly in the office
- Resistant to friction wear on trails
- Thermal comfort (less cold in winter, less sticky in summer than silicone)
The only limitations: less suitable for deep diving (prefer silicone), and takes a little longer to dry than silicone after immersion.
Leather: yes, it's possible, here's how
For: office, outings, dressed-up watch look
Many people think you can't put leather on a GPS running watch. Wrong - provided you follow two rules.
Rule 1: keep a silicone strap for sports. You don't run with leather. Period.
Rule 2: choose a supple leather, suitable for the rounded case of the Forerunner 255. A full-grain cowhide or a vintage patinated leather offers an interesting visual contrast on a black 255 - it transforms it from a "sports watch" to a "tool for demanding athletes who also go to the office."
Our Garmin leather straps from €24.99.
Titanium and steel: make your 255 chic
For: premium look, all-day wear with formal attire
The Milanese titanium on a Forerunner 255 is an underrated combination. Lightweight, flexible, adjusts precisely thanks to the magnetic clasp, and gives your 255 a jewel-watch look. The same goes for fine steel mesh.
Avoid: thick link styles like Fenix - too heavy on the 45.6mm case of the 255, they create a visual imbalance.
Compatibility with other Garmin models
A Quick Release 22mm strap purchased for Forerunner 255 also works on:
- Forerunner 265 ✅
- Forerunner 745 ✅
- Venu 2, Venu 3 ✅ (but different look, rounder case)
- Vivoactive 4 (45 mm only) ✅
- Instinct 2 ✅ (but very different look, square case)
- Marq (with aesthetic caution)
Does NOT work on:
- Forerunner 55, 165, 245, 265S → 20mm
- Forerunner 55, 55S → 20mm
- Forerunner 255S, Venu 2S, Venu 3S → 18mm or 20mm depending on model
- Fenix → proprietary QuickFit, never compatible with Quick Release
- Instinct first generation → 22mm but non-standard proprietary system
How to install a Quick Release strap
The Quick Release 22mm straps for the Forerunner 255 can be installed without tools in 30 seconds.
To remove the old one:
- Turn the watch over, case facing you
- On each side of the strap, you will see a small bar
- Each bar has a small lever with a notch (often orange)
- Press this lever towards the center of the strap to retract the bar
- The strap will be released
To install the new one:
- Position the strap against the watch lug
- Press the lever on the bar to retract it
- Slide the bar into the lug hole
- Release: the bar will click into place with a spring
- Check that the strap is securely attached by pulling lightly
No screws, no tools, no risk of scratching the case.

View bracelet →Frequently asked questions
Is a Forerunner 265 strap compatible with the 255?
Yes. The Forerunner 255 and 265 (non-S versions) use the same 22mm Quick Release. All our straps are interchangeable between these two models.
What about the 255S?
No, the 255S uses 18mm. See our dedicated Forerunner 255S collection.
How to distinguish Quick Release and QuickFit?
Quick Release = classic watch spring bar, two small metal pins with a lever. QuickFit = Garmin's proprietary clip system, wider and more visible, usually with a clearly marked orange lever. The 255 uses Quick Release.
Should the strap be tight for accurate wrist heart rate monitoring?
Yes, a strap that is too loose will skew optical heart rate measurements. Tighten it enough so that the watch doesn't move on your forearm during exercise, without cutting off circulation.
Nylon or silicone for trail running?
Breathable military nylon is probably better - lighter, dries faster, better thermal comfort. Silicone remains unbeatable in the pool.
Can the Forerunner 255 be worn with a leather strap at the office?
Yes, provided you remove the leather strap for sports. A cowhide or vintage leather strap creates an interesting contrast with the 255's black case.
Where is shipping from?
Our European warehouse. France 3-7 working days, from €4.99, free for orders over €39.
Returns possible?
14 days to change your mind, in accordance with European law. For defects, 2-year legal warranty.
