Soft and cant strangle easily. Get to working out with that rich sound of in ear head phones. Pretty annoying and a waste of time. The actual speakerphone (Freeway) is 4" x 4. I have NEVER had issues with any popular brand sneaker. ???? These shoes feel fabulous from day one on my back, They are light and comfortable. Only one version. The ornamental buckles have prongs which stick straight out like spikes, and cannot be flattened. Then I put the 5s (4X) on the bottom center peg,& the locks on the top center pegs.
