Not quite solid enough
The lift could be a tiny bit higher but the most important downside is that the material these are made of ended up bending a bit after 4 weeks of squats. I squat twice a week and bought these so that I wouldn't have to pack my squat shoes for a flight home. While I was there I did squats twice a week and the max load I worked with weighed 365 (I weigh 180lbs). By the end of my stay home, the lifts were already starting to curve/bend like they were giving way to the weight. The material could be stronger which is why I gave them a lower rating. Overall, they were better than squatting flat footed or in squishy tennis shoes.
