The shoes tongue is thick which is usually great for keeping your feet in one place in your shoe as to prevent your foot from moving around too much when you run. (A foot that slides around your shoe even with a sock causes blisters, corns, and calluses). The stuffing used in the tongue is too dense making it feel like there is force against the foot pointing downwards and though it’s a light shoe; it feels like a relief to take it off. Those that have bunions should not buy these. The toe box is also too tight so the outer edge of fabric and the sole split the padding beneath my pinky toe.. which is really a callous.. under that callous is a bone.. so I’m jogging while that bone/callous are squeezed and wow that hurts! finally, the pressure wants to sit on the center foot pad directly beneath your toes.. the flat part between your two callouses everyone. The nerves there get angry! These shoes are for running and shoe companies have designed their advanced running shoes to cushion the impact running has on joints. This is a great thing.. but to make it a perfect shoe the tongue has to cover every toe softly.. the center of gravity needs to be spread evenly in the front.. and the front of the shoe needs to be wide. Everyone is different.. some people have chode toes and some people have for toes that look like they could play Bach on the piano yet both are considered a size 7; therefore, their foot pad lands in a different spots. This is why some running shoes are perfect and some don’t hit the mark. Lastly, I didn’t use these enough to know anything about the quality.. they feel standard good quality for a corporate shoe company.
