Inzer Forever Lever Belt
Strengths
- +IPF-approved — usable at federation competitions without modification
- +Lever buckle locks at a fixed circumference, so the belt is identical tight every set
- +Genuine leather, 4" width, 10 mm or 13 mm thickness options
- +Lifetime warranty — these belts genuinely outlast their owners with reasonable care
- +Trusted by competitive powerlifters for ~30 years — long enough that the failure modes are well documented
Weaknesses
- −Brand-direct only — Inzer's web store is the canonical source
- −13 mm thickness has a long break-in period (4-6 weeks of regular use before it stops feeling like cardboard)
- −Lever buckle limits day-to-day waist-size flexibility — refit takes a screwdriver
- −Inzer's customer service has a reputation for being slow on warranty claims; ship-time is also longer than Amazon-native brands
Adidas Powerlift 5 Shoes
Strengths
- +15mm raised heel (good for high-bar squats)
- +Hard EVA midsole (won't compress)
- +Single-strap secure fit
- +Sub-$130
Weaknesses
- −Synthetic upper (not leather like Adipower)
- −Narrow fit can pinch wide feet
- −Not as stiff as TPU heel shoes
