I like the silicone tips more. Overall its well worth the price! Car rides and quite times will never be the same. I had to reorder since their size was spot on. When I questioned the process I stopped hearing from that person. The swivel join at the base of the strap creates a bump on either side that presses into your foot arch uncomfortably especially when you put your weight on it. It feels like it I’ll probably be able to wear these in over time and if not, I’ll always have a secure sandal that’s soft and comfy. Nothing that he or I expected. When we tried to remove the entire rack from the hitch, it would not budge. I left more space at the top and and in between the rack sets and the bottles want to tip.
