Lotto Men’s Viper Ultra IV Speed Yellow



The Lotto Viper Ultra IV Speed offer great stability for a relatively light weight shoe. The value for money on the Viper Ultra is impressive. You’ll see from the images that the shoe has good wear protection around the toe and the outer sole features Longlast 40 tech for long lasting durabilty. Lotto is still relatively new in SA so how durable the Longlast 40 is yet to be determined. The breathabilty and flex is good on the shoe providing a decent upper for this price point. All in all the Vipers will have moving with ease and comfort on the courts and is definitely worth consideration.


  • Nylon upper with a 3D K-PU weave
  • PU foam insole
  • Dual density heel
  • High quality rubber
  • TPU shank and stabilizer
