Sizing Information

FirstGear sells these boots in US sizes. In trying them on, we found the boots to run about one size small than the stated size in the larger size boots and about a half size small in the smaller size range. We therefore recommend that you use our chart shown below to make a selection.

For each US boot size, there is a corresponding European size printed in each boot. The European sizes listed seem to be a good estimate of fit, so if you know your Euro size in most boots, then use our chart to select the “FirstGear Boot Size” based on your usual Euro size.

Why the inconsistency? We’re not sure, buy we speculate the boots are primarily manufactured in Euro sizes and the conversions to US sizes was not done correctly.

The width of these boots tends toward roomy. Some brands like Sidi and Tour Master are more narrow, perhaps a C or D width, and I’d estimate the width of these FirstGear boots as slightly more wide, say D or E. Other brands that run wider like these FirstGear boots are TCX and Alpinestars.

Our Two Cents

The Big Sky boots by FirstGear are an all-purpose mid-height riding boot. The boots offer an integrated waterproof liner to keep out water and include motorcycle specific safety features.

If you are looking for a good boot at a very reasonable price, I think this one might work well for you. The overall feel of the boot is quite good. The upper materials are sturdy feeling and the reinforcements in the shin, toe box and heel surround are all very well done. The weakest part of this boot is with the sole’s reinforcement which is kind of weak. Normally there are stiffeners across the instep of motorcycle boots to allow you to bear weight on pegs without the sole “folding up”, but this one is pretty flexible. I wouldn’t recommend this boot for any sort of adventure riding or any riding that routinely involves standing on your pegs, but for general street riding, it should be fine.

The styling here is quite nice and I like the bright reflective materials for night visibility. The boot feels great on the inside and should break in easily. The best weather conditions with this style will be nearly all temps other than very hot because there is no venting here. For cooler/cold and with or without wet weather, they should do the trick. For what you get here, the price is certainly more than fair. Be sure to read our sizing advice before ordering. :: Paul, 05-07-21
