Inov-8 shoes are fast becoming a favorite of mine.  I have the Roclite 280, the X-Talon 212, the Terraclaw 250, and now the Terraclaw 220.  I always go with the Standard Fit due to the wider toe-box.  The Terraclaw series is less aggressive than most of the Inov-8 trail/mud range of shoes.  The lugs on the bottom are smaller by a few millimeters, and the foot protection and rand are reduced to trim weight.  Traction is still remarkable, and there is enough at the front of the shoe to protect from minor bumping and impact.  The Terraclaw 220 has a unique tongue and lacing system, which is interesting, but not really anything needed, as I have not had trouble with previous model lacing.  The heel cup has some structure to it without chaffing or irritating the foot.  The lightweight TPU overlay across the top of the shoe provides stability to connect the upper to the outsole, and therefore keeps the foot onboard the shoe, reducing side slop.  The midsole and outsole combine to be very responsive through toe off, and provide good ground feel, yet they are comfy enough to wear all day.  Great shoes like this for $29 is one of the better buys I have made.
