Asics Gel Renma Review - Squash Source。The GEL-RENMA™ shoe is designed for court players looking to take their game to the next level. When you\'re performing multi-directional movements, you need a shoe that will help increase your stability and flexibility. The midsole\'s TRUSSTIC® technology improves support while reducing excessive twisting. Meanwhile, the wrap-up outsole is teamed with a wider gauge to create smoother and more balanced movements. Flex grooves in the outsole are strategically positioned to accommodate multi-directional movements. They help increase your flexibility so you can move more freely.
