⚡ Quick Answer
Buy the IronLifter 3 if: you want competition-grade performance with free UK & EU shipping, native EU sizing, British Powerlifting approval, 7 colorways, and a specialist brand built exclusively for strength sports — at £65–85 less all-in than the Adipower 3 for most UK buyers.
Buy the Adidas Adipower 3 if: you want the most recognised brand in weightlifting, prefer lace closure, or can buy it locally from a UK retailer at a competitive price.
Brand Background
Castiron Lift — Specialist Strength Sports Brand
Castiron Lift makes one thing: shoes for lifters. No running shoes, no lifestyle sneakers. Every design decision in the IronLifter 3 was made by competitive powerlifters and Olympic lifters. The shoe ships free to all UK and EU addresses, comes in native EU sizing (37–48), and is approved for British Powerlifting and IPF competition. Learn more about Castiron Lift.
Adidas — Global Athletic Brand
Adidas is one of the world’s largest athletic brands with strong UK and European retail presence. The Adipower line has been worn by elite Olympic weightlifters at World Championships and Olympic Games. The Adipower 3 is available through major UK sporting goods retailers including Decathlon, Sports Direct, and specialist weightlifting retailers. Visit Adidas UK.
The key distinction: Adidas is a generalist brand that makes weightlifting shoes. Castiron Lift is a specialist brand that makes only weightlifting and deadlift shoes. This focus matters for product refinement and value.

Heel Height & Construction
Both shoes feature ~22mm heel elevation — the competition standard for most powerlifting and Olympic weightlifting federations. Research in the Journal of Strength and Conditioning Research confirms that heel elevation in this range significantly improves squat depth and trunk angle, particularly for lifters with limited ankle dorsiflexion.
The IronLifter 3’s rigid TPU heel block is engineered for stability across both powerlifting squats and Olympic lifting. The Adipower 3’s TPU heel wedge has been refined across multiple generations. Both are competition-grade — real-world performance difference is negligible for most lifters. See: Weightlifting Shoes vs Flat Shoes — UK & Europe.
Upper & Materials
The IronLifter 3 uses a premium microfiber upper — lighter, more breathable, and requiring no break-in period. For UK lifters training in cooler gym environments, breathability is less critical than in warmer climates, but the no-break-in advantage remains significant for high-volume training blocks.
The Adidas Adipower 3 uses a synthetic/mesh upper. Well-engineered but typically requires 3–5 sessions to soften and conform to foot shape. The mesh panels improve breathability but reduce structural rigidity vs the IronLifter 3’s full microfiber construction.
Independent reviews from Garage Gym Reviews and Barbend consistently note that microfiber uppers offer better out-of-box comfort vs synthetic blends that require breaking in.
Strap Systems
The IronLifter 3 uses a double velcro strap system — two independent straps for separate tension adjustment across the midfoot and forefoot. Preferred by most competitive powerlifters for speed and repeatability at competition, particularly when switching between weightlifting shoes and deadlift shoes between attempts.
The Adidas Adipower 3 uses a lace + single strap system. Laces provide highly customisable forefoot fit but add time to the shoe-change process. Community consensus on r/weightlifting and r/powerlifting consistently favours velcro strap systems for competition use.

Real-World Use Cases
🏋️ The British Powerlifter competing at regional level
You compete under British Powerlifting rules, squatting in weightlifting shoes and pulling in deadlift shoes. You need a shoe that goes on fast between attempts and is confirmed competition legal. IronLifter 3 wins — British Powerlifting approved, double velcro for fast shoe changes, and £35–65 cheaper. See also: TurboLifter 1 vs TurboLifter 3 Pro for your deadlift shoe.
🏊 The British Weightlifter training at a club
You train cleans, snatches, and jerks 4–5 times per week at a British Weightlifting affiliated club. You need a shoe that’s comfortable from session one and stays comfortable across high-volume training. IronLifter 3 wins on comfort and value. The Adipower 3 is also excellent here, but the £35–65 premium is hard to justify when performance is comparable.
🏏 The CrossFit Athlete at a UK box
You need a shoe that handles squats, cleans, snatches, and occasional box jumps. IronLifter 3 wins — microfiber upper handles varied movement better, double velcro is faster to adjust, and it’s significantly cheaper.
🏆 The Competitor who wants Adidas on the platform
You want the Adidas three stripes at international competition. Adipower 3 wins on brand prestige. If the Adidas name matters to you at competition, it’s worth the premium. The IronLifter 3 is the better shoe on specs and value, but brand recognition is a real factor for some lifters.

Price & Value for UK/EU Lifters
The IronLifter 3 at ~£135 with free UK shipping vs the Adidas Adipower 3 at £170–£200 from UK retailers represents a £35–65 saving. Over a 2–3 year lifespan of regular training, that saving is significant — and the IronLifter 3 delivers equal or better performance on every metric that matters.
For European lifters, the IronLifter 3 at ~€160 with free EU shipping vs the Adipower 3 at €200–€240 represents a €40–80 saving.
Import Costs & UK Availability
The Adidas Adipower 3 is available from UK retailers, so most UK lifters won’t face import costs. However, stock availability varies — popular colorways and sizes sell out quickly, and UK retailers may not carry the full size range (37–48).
The IronLifter 3 ships directly from Castiron Lift to all UK and EU addresses with free shipping, full size range (EU 37–48), and all 7 colorways available at all times.
