"My neon green k-frame Rubios fit perfectly (size 11). The cushioning works well with my diabetic feet giving me a stable platform in all conditions."
"Great grip. Comfortable. Feels sturdy."
"Love these shoes."
"Only worn once so far. Felt very nimble in these shoes and encourages you to stay on your toes. These fit like a glove. Heel feels nice and locked in. Toebox width was snug for me and had some minor discomfort on side of one toe. Hoping there's some additional break in for the ideal comfort. Definitely meant for tennis and would not choose these for off-court as they are not super plush or forgiving."
"This shoe is amazing. It was playable right out of the box. The tread and sole provide excellent cushion and grip; the grip on the hard court is the best I've experienced. The tongue is well padded and provides great cushion so that the laces do not dig into the top of your foot. The laces are nice and thick, and hold really well. This shoe provides the best ankle support and heel lock down. I often have trouble with heel slippage, and these shoes prevent heel slippage completely. Plenty of room in the toe box and fits to size. The shoe is a bit higher at the ankle and fits like a sock, so it also provides superb lateral support. I've bought most of the major brands (Nike, Adidas, Wilson, Babolat, Head, Mizuno, New Balance, Fila, Diadora) of tennis shoes and play at least 4-5 times per week and this by far is the best shoe I've bought. It provides the right balance of speed, cushion, and support. I hope K-Swiss continues to produce this shoe, there is absolutely nothing that needs to be changed or "improved. " The only suggestion I have for K-Swiss is to produce it in more colors."
"It has narrow toe that I need. Good support for pivots and turns and runs. Size runs true to sizing info that was online in the sizing chart, and I measured my foot length to compare to chart."
"Excellent"
"Great model Shoes! Nice colors! Good way Rublo by Karis"
"Great fit. Good looking shoe."
