Query: Leg Lifter

I purchased this item after having hip replacement surgery. I was unable to lift my leg very high, needed help getting in my van and also my bath tub/shower. It worked fine when I had no shoes on. But, when trying to get into my van (of course, wearing shoes) the loop would not stay open in order to get my foot in while wearing Reeboks (the only type shoe I can wear). It would catch on the rubber soles, and I am unable to use it for the main purpose for which I bought it. I need a product with a rigid, stirrup-type loop for the foot.
