SIDI Tri-Sixty Triathlon Shoes Review 2026

What Is the SIDI Tri-Sixty?

The Tri-Sixty is SIDI’s dedicated triathlon shoe, built around the brand’s road-shoe construction quality but reworked for fast, sockless T1 transitions. It swaps SIDI’s usual multi-buckle closures for a single rotary dial system, paired with an integrated heel design intended to help the shoe stay open and ready to step straight into out of transition.

Verified Specs

• Price: £199 (RRP £360) at Tredz
• Sole: C-Boost SRS carbon sole with nylon/TPU inserts protecting the carbon from wear in the areas most affected by walking
• Closure: Single Xeler Techno 4 dial with durable Dyneema cables for instant micro-adjustable opening and closing
• Comfort: Tecno-3 Push Flex system to reduce pressure across the instep during closure
• Upper: Italian-made TechPro microfibre for ventilation and quick drying after the swim
• Safety: Reflective heel inserts for visibility in low light

Who Is It For?

This is a purpose-built triathlon shoe rather than a converted road shoe, which matters most if you’re racing sprint or Olympic distance and every second in T1 counts. The single-dial closure is faster to operate one-handed while moving than a double-strap system, and the carbon sole gives real stiffness for power transfer despite the shoe’s transition-focused design. For long-course racing where you’ll spend four-plus hours in the shoe, the padded liner holds up reasonably well, but riders coming from a heavily cushioned road shoe may notice the firmer, race-oriented fit.

Buying Tips

• Practice your T1 routine with the shoes pre-clipped into your pedals before race day — the quick-entry design only saves time if you’ve rehearsed sliding your foot in on the move.
• SIDI’s sizing tends to run true to EU sizing but check the size chart against your usual road shoe, since the triathlon-specific last differs slightly from SIDI’s road range.
• The single dial is fast but offers less fine-tuned adjustment than a two-strap system — if you have unusually wide or narrow feet, try before you buy where possible.

Care and Maintenance

Rinse the shoes with fresh water after every open-water swim to clear salt or chlorine from the dial mechanism and upper. Let them air-dry away from direct heat, since sustained warmth can affect the carbon sole’s stiffness and the dial cable’s durability over time.
