Ok.. I usually wear my good sneakers with orthodics for walking. but july is hot. I also use birkenstocks sandals which have given me good support in the past. but last summer I tore the meniscus? in knee, had it fixed; and the birkenstocks are 3 summers old and definitely have wear on the soles- and need to be replaced. Can anyone who has had similiar problems recommend a sandal like shoe that will be good for my knees?? (and feet too 
thanks Jill
