The debate over squat shoes versus flat shoes has been a fixture in strength training communities for decades. It's also, in most cases, the wrong question.
The right question is: what are you trying to do, and what does your body need to do it? The answer determines the shoe.
What a Heeled Squat Shoe Does
A heeled squat shoe raises your heel relative to your forefoot. The Ronin Lifters uses a 20mm heel. That elevation compensates for limited ankle dorsiflexion — the range of motion that allows your shin to travel forward during the squat descent.
When your ankle can't flex enough, your heel comes up or your torso tips forward — usually some of both. Heel elevation solves this by changing the geometry: your shin angle becomes more vertical relative to your foot, which lets you stay upright without demanding more from your ankle than it can give.
For most athletes, the result is better depth and a more upright torso, which means more quad engagement and a cleaner bar path. For competitive athletes, it often means hitting legal depth consistently.
What a Flat Shoe Does
A flat, zero-drop shoe keeps your heel and forefoot at the same level. This maximises floor contact area, maintains your natural hip-to-heel relationship, and — for deadlifts specifically — keeps your hips as close to the bar as your anatomy allows.
Flat shoes are what you want for deadlifts (all variations), Romanian deadlifts, hip hinge work, and squat patterns where you have the ankle mobility to maintain position flat-footed. Same for strongman carries, general strength training, and any movement where hip-hinge mechanics dominate.
Which One Do You Need?
If you deadlift seriously: You need a flat shoe. A heeled shoe adds leverage that works against you on a pull. The Radix Pro or Radix are built for this. Deadlift slippers (Sumo Sole Gen 4, Notorious Lifters Gen 3) go even further if deadlift specialisation is your focus.
If you squat and struggle with depth or upright position: Try a heeled shoe. The Ronin Lifters' 20mm heel gives you a clear test — if your squat improves significantly, heel elevation is solving a real problem. If it makes little difference, your ankle mobility isn't the limiting factor.
If you do both seriously: You need both. A heeled shoe for squatting, a flat shoe for pulling. Two pairs, two use cases, no compromises on either end.
If you do general strength training without competition goals: Start with a flat shoe. It covers more movements at a higher level — deadlifts, rows, presses, carries, and general training. Add a heeled shoe when your squat mechanics become the ceiling.
What About Ankle Mobility?
Ankle dorsiflexion is the critical variable. If you can touch knee-to-wall with your heel flat and your foot 10–12cm from the wall, you can probably squat effectively flat.
If you can't, heel elevation is the appropriate accommodation for your anatomy — not a crutch. Ankle mobility can be improved over time, but a heeled shoe is the right tool to squat at your best while you work on it.
The Complete Footwear Strategy
Most strength athletes end up with two pairs. The exact models depend on your training focus:
- Powerlifting focus: Ronin Lifters for squat, Radix Pro or Sumo Sole Gen 4 for deadlift
- Strongman focus: Ronin Lifters for overhead and squat events, Radix Pro for everything else
- General strength training: flat shoe first (Radix or Radix Pro), heeled shoe added when squat mechanics are the limiting factor
