Very disappointed in these shoes because the &#34;neoprene&#34; style of fabric at the upper edge above the instep tends to &#34;grip&#34; the skin and thus move the shoe down the foot with each step. Particularly dangerous when driving because this same effect forces the foot out of alignment with the sole making it impossible to move from gas to brake.<br /><br />Sole is fine. Keen's toe-cap design is great. Just not wearable, sent them to Goodwill after 3 weeks.
