I like these shoes a lot. They are a lot more comfortable than Butterfly and Mizuno shoes I've had in the past. They look less dorky than most other table tennis shoes as well. They just look like a normal pair of sneakers really. The toe box is slightly less wide than other brands I've tried, which I actually like. The grip on these is good on wood floors and probably even better on proper rubberized table tennis flooring. The vents and air holes in the soles help keep your feet cool and dry.
When I first got the shoes and was putting the laces in, I noticed that the top eyelets on each shoe weren't properly punctured all the way through. I had to use a tool to poke the eyelets open so I could finish lacing up the shoe. Other than that the actual construction quality seems very high. Definitely give these a try if you're looking for a comfortable TT shoe that's cheaper than equivalent butterfly or mizuno shoes.
