Limitup, these look very good for ankle support. They are the
Head Strong Mid shoes. Maybe try them?. Tennis Warehouse sell them:
See how the are sort of higher at the top than most tennis shoe? They must be great for protecting the ankle.
Here's a review I found on the shoe's foot support/stability:
Although the slightly wide fit of the HEAD Strongs provided better support to our wider footed team members, even our resident narrow foots found adequate support. Granville said, "while the shoe is quite comfortable, it does seem a bit roomy in the toe box for my feet. I like the more contoured interior and glove-like fit that I find in a shoe like the Adidas Barricade. This shoe just didn't provide that fit for me, otherwise it would rival some high-end performance shoes for comfort and fit. Overall, I found this an adequately stable shoe for all but the most competitive play."
John found the HEAD Strongs to be supportive and stable. He said, "the soft and supple leather construction provided ample support when moving forward or laterally.
I never was in danger of rolling an ankle or coming out of these shoes."
Chris also said the HEAD Strong shoes held his feet pretty well, adding, "although the fit was a little wide, the velcro strap across the lace system helped me get a fairly secure fit. I still had some slight slipping inside the toe box of the shoe on side to side movements. It wasn't enough to cause me blisters or lose a lot of stability, but it was noticeable nonetheless. I was surprised at how well the supple uppers supported my foot in the heel area, and I seemed to get a better fit in this part of the shoe. My feet also felt low to the ground in the HEAD Strongs, and I think this gave me a more secure feeling on court."
With his wide feet, Danny found the HEAD Strongs to provide good fit and support. Danny said, "the mid cut design and adjustable leather strap gave me great support and stability. I never experienced any slippage during the playtest of these shoes."
