I've never gone to clipless. I moved from a cleated road shoe to a Specialized Sonoma, that I can walk in, 5 or 6 years ago. So I still use toe clips and straps but I don't need to tighten or loosen them anymore. On my mountain bikes I use platform pedals with hiking shoes. So far I have not had any desire to go clipless. As for toe clips, I have found Large and X-Large Christophe on ebay for my wife. I am still running DA 7400 pedals.
