Shipping Information
This item is listed as final sale and not eligible for returns or exchanges.
Our inventory of Notorious Lift shoes is constantly changing, and many colours are limited in availability.  If the size you desire is no longer showing up as an option, it is likely that we will not be restocking that size in this colour.

If you ask most lifters what's the first thing you should get for equipment for training the answer will often be shoes. Look around at other sports, do you see football or baseball players playing in running shoes, no, they are wearing the right shoes for the sport. Stop trying to lift heavy in soft, squishy shoes. The Notorious Lift line of lifting slippers puts you as close to the ground as possible, removing any instability from a soft shoe. 

Execution is at the forefront of the design for Sumo Sole Gen 2.5. The slipper features a newly designed Fortis sole that infuses the strengths of two existing soles. They took the ultra-thin thickness of the Notorious Lifters and paired it with the Sumo Sole’s brawny side lateral wall. They found a happy medium for the lateral height that would be comfortable to wear for the duration of a workout but would also prevent any spillage during heavy pulls.

Key Features:

  1. Ultra-thin sole (2.7mm) with a wide toebox for enhanced sensory feedback and less pulling distance.
  2. Special blend of rubber for a lighter, more durable and enhanced flexibility feel without sacrificing comfort.
  3. AdvanKnit features a lightweight, breathable stretch knit that contours to your feet while still providing a tight feel to ensure proper lockdown and comfortability.
  4. Custom milled nylon strap with a rubber tab strategically placed on the metatarsal for complete lockdown.
  5. Internal and external heel counters that confidently anchors your heel down to prevent over-pronation.

Perfect slips

Comfy, grippy, does exactly what you'd want them to.

Easy purchase

I wear a size 40 and based on the reviews purchased a size 39. The length is good but my wide foot is feeling a bit boxed in. I contacted Inner Strength and they tell me they will stretch a bit over time but also offered to swap them out for a very reasonable $8 shipping fee. I decided to keep them. Truth be told, once I’m lifting the comfort of my foot goes out of my mind. My foot felt very planted when doing sumos. No movement at all. So far I am very pleased, with the shoe and Inner Strength. Excellent communication, a pleasure to deal with.

Great shoes but a loop snapped two months into use

I got these shoes as a gift and I love them so much but it breaks my heart to see the loop holding the strap break

Inner Strength Products

Hey Sal I'm sorry to hear about the ring. There has been a small number of the Gen 2.5s that have exhibited this issue. We have sturdier replacement rings that we can ship out and you can easily slide on yourself to fix the shoe, I'll reach out to you from our support email to get that squared away.

Love them!

Loved the shoes but the size is bigger and my size is not in stock under any color.


Inner Strength Products

Hey Sandal! Sorry for the inventory issues, we do our best to keep as many options in stock at all times but it can be difficult to predict demand and some products have especially long lead times for restocks.
