I got these right before having kids and they never really fit. I wore them less than 10 times so enemy though they’re a couple years old they are like new.
Here is the full description I found on the shoe:
The new Tri N 1 was built for pure performance when it counts—on race day. This is the short course specialist—blazing quick transitions and fast and light to the finish. The quick-draining and breathable mesh upper keeps your feet cool and dry, and the updated E:MOTIONTM midsole promotes a smooth and efficient turnover running style.
New 3-D Seamless Print Upper Technology adds lightweight structure and upper integrity
Transfer Dry spacer mesh keeps feet cool and dry
Sock-like upper construction and quick lacing system provide lightning-fast transition times
New Dynamic offset-shaped E:MOTIONTM midsole is biomechanically tuned for a neutral to supinator running gait
1:1 Energy Foam in forefoot cushions upon impact and returns energy back to the runner during propulsion
Blown rubber in the forefoot and Carbon Rubber in the crash pad combine for great cushioning and abrasion resistance
Dynamic Offset: 1 mm at initial contact to 4.5 mm at mid-stance
Heel Stack Height: 19 mm (includes midsole and outsole)
Weight–Size 8: 8.1 oz, 229 g
