Shoes w/ Lateral support

[magnetmaker]

Hey everyone, I hope this is the appropriate forum for this question. Essentially I'm looking for indoor court shoes for squash with good lateral support, I wouldn't mind buying court specific shoes, but if there are other suggestions, I would be open to trying them. For example, I hear that cross trainers are acceptable, and they have more cushioning which makes it easier on the knees (my left knee gets sore occasionally)Thoughts on the Nike Free series of shoes?Thanks in advance!
